We are given two strings, A
and B
.
A shift on A
consists of taking the string A
and moving the leftmost character to the rightmost position. For example, if A = 'abcde'
, then it will be 'bcdea'
after one shift on A
. Return True
if and only if A
can become B
after some number of shifts on A
.
Example:
Input: A = 'abcde', B = 'cdeab'
Output: true
Approach
C++
#include <bits/stdc++.h>using namespace std;bool rotateString(string A, string B){int n = A.size();int m = B.size();if (n != m)return false;if (A == B)return true;int t = n;while (t--){string x = "";char temp = A[0];for (int i = 1; i < n; i++)x += A[i];x += temp;A = x;if (A == B)return true;}return false;}int main(){string A = "abcde";string B = "cdeab";if (rotateString(A, B)){cout << "true";}else{cout << "false";}return 0;}
