Can I know where I am going wrong in the code because out of 5. 3 are correct and 2 are wrong. It’s snail climb project.

Question

function main() {
var depth = parseInt(readLine(), 10);
//your code goes here
var i=0;
var up=7
var down=2
var day=5
var days=0
while (i<depth){
i+=day
days++
}console.log(days)

}

Answer 1

Rethink Condition :
Snail Climb 7 feets. If it not reached destination, then only it falls 2 feets. ..
This repeated until reaching destination.
Where are using values for up, down?
