Ejemplos:
C++
// CPP program to replace c1 with c2 // and c2 with c1 #include <bits/stdc++.h> using namespace std; string replace(string s, char c1, char c2) { int l = s.length(); // loop to traverse in the string for (int i = 0; i < l; i++) { // check for c1 and replace if (s[i] == c1) s[i] = c2; // check for c2 and replace else if (s[i] == c2) s[i] = c1; } return s; } // Driver code to check the above function int main() { string s = "grrksfoegrrks"; char c1 = 'e', c2 = 'r'; cout << replace(s, c1, c2); return 0; }
Java
// Java program to replace c1 with c2 // and c2 with c1 class GFG { static String replace(String s, char c1, char c2) { int l = s.length(); char []arr = s.toCharArray(); // loop to traverse in the string for (int i = 0; i < l; i++) { // check for c1 and replace if (arr[i] == c1) arr[i] = c2; // check for c2 and replace else if (arr[i] == c2) arr[i] = c1; } return String.valueOf(arr); } // Driver code public static void main(String []args) { String s = "grrksfoegrrks"; char c1 = 'e', c2 = 'r'; System.out.println(replace(s, c1, c2)); } } // This code is contributed // by ChitraNayal
