Remove duplicates from a string using STL in C++
Given a string S, remove duplicates in this string using STL in C++
Examples:
Input: Geeks for geeks Output: Gefgkors Input: aaaaabbbbbb Output: ab
Approach:
The consecutive duplicates of the string can be removed using the unique() function provided in STL.
Below is the implementation of the above approach.
#include <bits/stdc++.h>using namespace std; int main(){ string str = "aaaaabbbbbb"; sort(str.begin(), str.end()); // Using unique() method auto res = unique(str.begin(), str.end()); cout << string(str.begin(), res) << endl;} |
Output:
ab
