I keep getting an execution time out from my code for the challenge, Am I doing something wrong?

Question

I am trying to do the Snail in the well JavaScript challenge and I have come up with the following code to try and solve it:

Problem:

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.

My Code:

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

for (i = 0; depth > 0;i++){
day = (depth+2)-7;

}
console.log(day);
}

I keep getting execution timed out as an output which i am not expecting at all. Am I doing something wrong with my code? Or is it a problem on Sololearns end?

Answer 1

function main() {

var depth = parseInt(readLine(), 10);

//your code goes here

let climb = 0;

let days = 0;

while(true){

days++;

climb += 7;

if (climb >= depth){

break;

}

climb -= 2;

}

console.log(days);

}

Is the your problem?

Answer 2

Isn't that for loop infinite?

Answer 3

You don't change depth, but use it as condition in the loop. So the loop runs forever

Answer 4

function main() {
var depth = parseInt(readLine(), 10);
var a=depth;
var b=0;
for (x=5;true;x+=5) {
if (x>a+2){
break;
}
b=b+1;
}console.log(b);

}

Answer 5

Okay I have managed to solve the challenge using the following:

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

let day = Math.round(depth/5);

console.log(day);
}

But it is isn't using a loop. I am a bit lost in how to apply a loop for this problem as my natural reaction was to use the code I have just written above.

How could I write a loop to solve this challenge?
