#716. Counting multiples

when green flag clicked
set [i v] to (0)
set [c v] to (0)
repeat (36)
change [i v] by (1)
if <((i) mod (4)) = (0)> then
change [c v] by (1)
end
end

# When the green flag is clicked
i = 0
c = 0
for _ in range(36):
    i += 1
    if (i % 4) == 0:
        c += 1

// Scratch's mod gives a positive remainder even for negative numbers
function mod(a, b) {
  return ((a % b) + b) % b;
}

let i = 0, c = 0;

// When the green flag is clicked
i = 0;
c = 0;
for (let j = 0; j < 36; j++) {
  i += 1;
  if ((mod(i, 4)) === 0) {
    c += 1;
  }
}
