Theory for this problem
+
Translate the story into a small arithmetic formula. Use ceiling division `(a+b-1)/b` when a partially filled unit still counts.
Connection to “Workers Needed”: here, intermediate values are best kept in named variables so the formula stays readable and data types remain clear.

Hints
+
['Identify what each input value means before writing the formula.', 'After solving “Workers Needed”, verify the algorithm on your own small example and on an allowed boundary case. Print only the required result with no extra text.']
ANSWER
Solution
+
#include <iostream>
using namespace std;
int main() {
long long work, capacity;
cin >> work >> capacity;
cout << (work + capacity - 1) / capacity << '\n';
return 0;
}
