Consider above example, suppose we need to check whether string 2 is a rotation of string 1. To find this, we concatenate string 1 with string 1. Then, try to find the string 2 in concatenated string. If string 2 is present in concatenated string then, string 2 is rotation of string 1. String 2 deabc is found on the index 3 in concatenated string. So, deabc is rotation of abcde.
Write a c program to reverse a string without using string functions. The simplest way to reverse a string in C is to use strrev function. But in this article, we will learn how we can reverse a string without using strrev or any other standard library function. We can reverse a given string by simply swapping ith character from the start and ith character from the end of the string. Each pair of characters is only swapped once.
Given a string S. The task is to print all the possible rotated strings of the given string. Skip to content. Related Articles. StringBuffer sb;.
In this program, we need to rotate the elements of array towards its right by the specified number of times. An array is said to be right rotated if all elements of the array are moved to its right by one position. One approach is to loop through the array by shifting each element of the array to its next position. The last element of the array will become the first element of the rotated array.
