Inserting Elements using Iterators

Medium STL Iterators

Solve in Playground →

Problem Statement

Write a C++ program using `std::vector::insert` with iterators to insert an element at a specific position.

Input Format

First line: N and Position index K. Second line: N integers. Third line: Value to insert.

Output Format

Print modified vector elements separated by a space.

Constraints

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

Sample Input

4 2
10 20 30 40
99

Sample Output

10 20 99 30 40

Explanation

Iterators specify exact insertion points for container methods.

Starter Code

#include <iostream>
#include <vector>

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

    }
    return 0;
}
