Approach:
The consecutive duplicates of the string can be removed using unique() function provided in STL.
Below is the implementation of the above approach.
#include <bits/stdc++.h>using namespace std; int main(){ string str = "Geeksforgeeks is best"; // Using unique() method auto res = unique(str.begin(), str.end()); cout << string(str.begin(), res) << endl;} |
Output:
Geksforgeks is best
