(Solved)I wonder, the answers sum = 9 if depth =42, how about you guys?

Question

function main() {
var depth = parseInt(readLine(), 10);
//your code goes here
sum = 0
j = 0

for(i=0; j < depth; i++){
j = j+5
sum += 1
}
console.log(sum)
}

Answer 1

Variable <i> is not necessary here, so we can safely remove it. Maybe this snippet can explain where <sum> got its value.

function main()
{
var depth = 42;
var sum = 0;
for (var j = 0; j < depth; j += 5)
{
console.log(j);
sum += 1;
}
console.log(sum);
}

I see, thank you 🙏🙏🙏. So, var i adds extra number 😇
