[SOLVED] There are some problem in my code. Please help!

Question

***The Snail in the Well***
The snail climbs up 7 feet each day and slips back 2 feet each night.
How many days will it take the snail to get out of a well with the given depth?

Sample Input:
31

Sample Output:
6

Explanation: Let's break down the distance the snail covers each day:
Day 1: 7-2=5
Day 2: 5+7-2=10
Day 3: 10+7-2=15
Day 4: 15+7-2=20
Day 5: 20+7-2=25
Day 6: 25+7=32
So, on Day 6 the snail will reach 32 feet and get out of the well at day, without slipping back that night.

Answer 1

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

while(1){
feet += 7;
i++;
if(feet >= depth){
break;
}
else{
feet-=2;
}
}

console.log(i)
}
