Snell in the well problem of JS course

Question

I got stuck at this problem. I don't get why this code isn't working. Can anyone give me hint ?
function main() {
var depth = parseInt(readLine(), 10);
//your code goes here
var
depth1 = 0,i = 1;
do
{

depth1 +=5;
i++;

}while((depth1 + 7)<=depth);
console.log(i);
}

Answer 1

„The snail climbs up 7 feet each day and slips back 2 feet each night.“
In your code you do not check separatly as well as first, what value has depth in a day before night. Thus in cases where the depth1 will be reached during a day the result is by 1 more. For example for input 42 your result is 9 and should be 8.

Answer 2

The hint will be to read carefully the description and do what you there see. If you like this will help you:
