(solution) Write a program to remove all the duplicate characters from a given input String e.g.if given String is "Java" then output should be "Java".(solution) Write a program in any programming language you to find the first non-repeated character in a given String, for example, if given String is "Java" then first non-repeated character is "J" 10) How to reverse the words in a given String sentence?
Why String is Immutable in Java but rather based upon the string data structure and require a lot of coding practice to solve them in limited time.
1) How to find the maximum occurring character in given String?
I have also provided the links to solutions for most of the questions so that you can quickly check your answer and code.
Remember, it's not just important to solve the problem but also to understand the solution and improve it gradually.
For example, if the first String "India is great" and second String is "in" then output should be "da s great" 5) How to check if two strings are rotations of each other?
(solution) Write an efficient program to test if two given String is a rotation of each other or not e.g.The second or further occurrence of duplicate should be removed.3) How to print the duplicate characters from the given String?A string is one of the most popular data structure, probably next to the array and that's why you will find at least one question from String in any programming job interview.If you don't know, String is nothing but a character array in most of the language like C.You can use all the tips and tricks you learned by solving array based coding question to also solve String e.g.reversing a String is the same as reversing an array and so on.(solution) Write an efficient Java/C/Python/Ruby program to return the duplicate characters from given String, for example if given String is Similarly, if input is "Java and Java Script" then your program should print "J", "a" and "v". 4) How to remove characters from the first String which are present in the second String?(solution) Write an efficient Java/c/Python function that takes two strings as arguments and removes the characters from the first string which are present in the second string.But, in Java, String is an object, which holds data in character array.This means you can solve many String based problem by assuming it as a character array.
