Program to check if first and the last characters of string are equal
We are given a string, we need check whether the first and last characters of the string str are equal or not. Case sensitivity is to be considered.
Examples :
Input : university Output : Not Equal Explanation: In the string "university", the first character is 'u' and the last character is 'y', as they are not equal, "Not Equal" is the output. Input : racecar Output : Equal Explanation: In the string "racecar", the first character is 'r' and the last character is 'r', as they are equal, "Equal" is the output.
C++
// C++ program to check if the first // and the last characters of a string // are equal or not. #include<iostream> using namespace std; // Function to check if the first // and the last haracters of a // string are equal or not. int areCornerEqual(string s) { int n = s.length(); if (n < 2) return -1; if (s[0] == s[n - 1]) return 1; else return 0; } // Driver code int main() { string s = "GfG"; int res = areCornerEqual(s); if (res == -1) cout<<"Invalid Input"; else if (res == 1) cout<<"Equal"; else cout<<"Not Equal"; } // This code is contributed by // Smitha Dinesh Semwal |
