Maximum substring alphabetically java

Given a string as an input. We need to write a program that will print all non-empty substrings of that given string. We can run three nested loops, the outermost loop picks starting character, mid loop considers all characters on right of the picked character as ending character of substring.

The innermost loop prints characters from currently picked starting point to picked ending point. Method 2 Using substr function s. This article is contributed by Harsh Agarwal. If you like GeeksforGeeks and would like to contribute, you can also write an article using contribute.

In this Java post, we will learn all about these. So, in the output, we must return the first lexicographically smallest substring and the last lexicographically largest substring as two newline-separated values i. Your email address will not be published. Please enable JavaScript to submit this form. First line input: a string s. The Format of Output: The respective lexicographically the smallest and the largest substrings of the string s as a single newline-separated string.

I need to create a summary table at the end of a log with some values that are obtained inside a class. The table needs to be printed in fixed-width format. I have the code to do this already, but I need to limit Strings, doubles and ints to a fixed-width size that is hard-coded in the code. I am thinking I need to do something in the constructor that forces a string not to exceed a certain number of characters. I will probably cast the doubles and ints to a string, so I can enforce the maximum width requirements.

I don't know which method does this or if a string can be instantiated to behave taht way. Using the formatter only helps with the fixed-with formatting for printing the string, but it does not actually chop characters that exceed the maximum length. To ensure you are not getting an IndexOutOfBoundsException when the input string is less than the expected length do the following instead:.

If you want your integers and doubles to have a certain length then I suggest you use NumberFormat to format your numbers instead of cutting off their string representation. You can also use String. The first digit is the minimum length the string will be left padded if it's shorterthe second digit is the maxiumum length and the string will be truncated if it's longer. You can use the Apache Commons StringUtils. If you just want a maximum length, use StringUtils.

No if or ternary? Left Documentation.

Ideally you should try not to modify the internal data representation for the purpose of creating the table. Whats the problem with String. It will return you new string with required width. The solution may be java. Learn more. Limiting the number of characters in a string, and chopping off the rest Ask Question. Asked 8 years, 4 months ago. Active 2 months ago.

Viewed k times. So, suppose I want to print a fixed-width table with int,string,double,string int,string,double,string int,string,double,string int,string,double,string and the fixed widths are: 4, 5, 6, 6.

If a value exceeds this width, the last characters need to be cut off. So for example:difference, Given a string. The task is to find the maximum number Psuch that given string can be partitioned into P contiguous substrings such that any two adjacent substring must be different.

More formally and. We can not divide it more than four parts, if we do then the condition will not satisfy. If you like GeeksforGeeks and would like to contribute, you can also write an article using contribute.

Improved By : mohit kumar 29ihritik. Load Comments.Given a string of length consisting of lowercase alphabets. The task is to find the number of such substrings whose characters occur in alphabetical order. Minimum allowed length of substring is 2.

For a substring to be in alphabetical order its character are in same sequence as they occur in english alphabets. For finding total number of substrings which are in alphabetical order traverse the given string and compare two neighboring characters, if they are in alphabetic order increment the result and then find then next character in string which is not in alphabetic order to its former character.

Code Review Stack Exchange is a question and answer site for peer programmer code reviews. It only takes a minute to sign up. I'm solving this problem from codeforces. But the time limit exceeds on some of the test cases. The problem statement is:. High school student Vasya got a string of length n as a birthday present.

This string consists of letters 'a' and 'b' only. Vasya denotes beauty of the string as the maximum length of a substring consecutive subsequence consisting of equal letters. Vasya can change no more than k characters of the original string.

What is the maximum beauty of the string he can achieve? Print the only integer — the maximum beauty of the string Vasya can achieve by changing no more than k characters. I can't understand how to reduce time taken by the code.

Is there any other solution or approach available? Yes, you can tackle this problem is a much faster way, with an O n algorithm, using a left and a right pointer delimiting the substrings to consider.

For each character in the input String, the idea is to keep an array counting the number of 'a' and 'b' between a given left pointer, that will represent the start of the substring, and the current character. When the count of each 'a' or of each 'b' is less than the allowed number of characters to change, we can consider making the change and incrementing the answer.

Lexicographical Smallest & Largest Substring of a given Length in JAVA

Then, when both of those 2 counts becomes greater than the allowed number of characters to change, it means we cannot change more characters so we hit a maximum length: the left pointer is increased, and the count of the character at that pointer is decreased.

The count of 'a' and 'b' characters can be modeled as an integer array index 0 corresponds to the count of 'a' while index 1 corresponds to the count of 'b'. At the moment, the entirety of the solution is in your main method. More often than not, in OOP, your main method should be reserved to be the entry point of your program only, rather than the entire program. This helps to keep your code better organized, and easier to understand and maintain.

In this particular case, I would move the code that actually solves the problem to another class, to help make it more general, and just read the input and print the output in main. There a few naming concerns that stood out. First, the problem states the input numbers are n and kwhich are often used for mathematical notation as a matter of convention; however, those don't necessarily translate well to code, as code should preferably be written in such a way that it makes the intentions clear.

We will extract that logic to a separate method as well. We can eliminate your char z and just return the result directly from the method. We can also simplify the return by using Java's ternary operator instead of if-then-else structure.

We can also leverage the fact that the length of the string is provided as input, and save ourselves a String.The String class represents character strings.

All string literals in Java programs, such as "abc"are implemented as instances of this class. Strings are constant; their values cannot be changed after they are created. String buffers support mutable strings. Because String objects are immutable they can be shared. Case mapping is based on the Unicode Standard version specified by the Character class.

String concatenation is implemented through the StringBuilder or StringBuffer class and its append method. String conversions are implemented through the method toStringdefined by Object and inherited by all classes in Java. Unless otherwise noted, passing a null argument to a constructor or method in this class will cause a NullPointerException to be thrown. A String represents a string in the UTF format in which supplementary characters are represented by surrogate pairs see the section Unicode Character Representations in the Character class for more information.

Index values refer to char code units, so a supplementary character uses two positions in a String. The String class provides methods for dealing with Unicode code points i. Since: JDK1.

This method does not properly convert bytes into characters. This method does not properly convert characters into bytes. Methods inherited from class java. This comparator is serializable. Note that this Comparator does not take locale into account, and will result in an unsatisfactory ordering for certain locales. The java. Since: 1.
