What did I do wrong? Pls help

Question

#include <iostream>
using namespace std;

int main() {
//your code goes here
int bus=50;
int input, remainder;
cin>> input;

while(remainder > 49){
input - bus = remainder;
}
int bus % remainder = ans;
cout << ans;
return 0;
}

Answer 1

Equation must be in the right side of the assignment operator, and the result will stored left side of assignment operator .

That is,
remainder = input - bus; (inside the while loop)
int ans = bus% remainder;

Answer 2

No need to use while loop you can directly get the result.
What did I do wrong? Pls help

#include <iostream>
using namespace std;

int main() {
//your code goes here
int bus=50;
int input, remainder;
cin>> input;

remainder= input - bus ;

int ans= bus % remainder;
cout << ans;
return 0;
}

Here you go.

Answer 3

Timeout is happening because if comparing an uninitialized variable. But i think there are some more mistakes. I tried to fix it for you, is that how the code should work?

#include <iostream>
using namespace std;

int main() {
//your code goes here
int bus=50;
int input, remainder;
cin >> input;
remainder = input;
while(remainder > 49) {
remainder -= bus;
}
cout << bus - remainder;
return 0;
}

But there is also a way without a loop, which performs much faster, especally for high input numbers.
Just modulo the input with the bus size to get passengers in the last/not full bus and substrakt that from the bus size to get the empty seats

Answer 4

This was my solution without loop:

#include <iostream>
using namespace std;

int main() {
//your code goes here
int waiting;
cin >> waiting;
int left_seat = 50 - waiting % 50;
cout << left_seat;

return 0;
}

Thx but I'm getting a...
