Simply put, the problem asks to print integers starting from \(A\), incrementing by \(D\), up to \(B\). One can implement it by appropriately using a for statement or a while statement.

Sample code (C++)

#include <bits/stdc++.h>
using namespace std;
int main(){
  int a, b, d;
  cin >> a >> b >> d;
  for(int n=a; n<=b; n+=d){
    cout << n << (n==b?'\n':' ');
  }
}

Sample code (Python)

A,B,D = map(int,input().split())
print(*range(A,B+1,D))
