Hello, This problem comes when we use else if statement and do some mistake more describe is given below.........

This post is may very short because my only aim was to describe this problem. Thank you, Keep supporting.............

Permutations of Strings hackerrank solution in C || Permutations of Strings

  Permutations of Strings Strings are usually ordered in lexicographical order. That means they are ordered by comparing their leftmost different characters. For example,   because  . Also   because  . If one string is an exact prefix of the other it is lexicographically smaller, e.g.,  . Given an array of strings sorted in lexicographical order, print all of its permutations in strict lexicographical order. If two permutations look the same, only print one of them. See the 'note' below for an example. Complete the function  next_permutation  which generates the permutations in the described order. For example,  . The six permutations in correct order are: ab bc cd ab cd bc bc ab cd bc cd ab cd ab bc cd bc ab Note:  There may be two or more of the same string as elements of  . For example,  . Only one instance of a permutation where all elements match should be printed. In other words, if  , then print either   or   but not both. A three element array having t
