Erasing Elements using Iterators

Medium STL Iterators

Solve in Playground →

Problem Statement

Write a C++ program using `std::vector::erase` with iterators to remove an element at a specific index.

Input Format

First line: N and Position index K. Second line: N integers.

Output Format

Print vector elements after erasure separated by a space.

Constraints

1 <= N <= 1000, 0 <= K < N

Sample Input

4 1
10 20 30 40

Sample Output

10 30 40

Explanation

Erasing via iterators shifts subsequent elements and shrinks vector size.

Starter Code

#include <iostream>
#include <vector>

int main() {
    int n, k;
    if (std::cin >> n >> k) {
        std::vector<int> vec(n);
        for (int i = 0; i < n; i++) std::cin >> vec[i];
        
        // Write your iterator erasure logic here

    }
    return 0;
}
