Is there a simpler way

Question

function main() {
var d = parseInt(readLine(), 10);
sum = 0
i=1
a=5
while(sum<d){

if(sum >= d-7){
a = 7;
console.log(i)
}
sum+=a
i++
}

}

Answer 1

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.

This is the question

Ok thanks i will look for them.

Answer 3

Probably this work

function main() {
var depth = parseInt(readLine(), 10);
//your code goes here
var day = 0;
var snailPosition = 0;
var morning = 7;
var night = 2;
while(true){
snailPosition += morning
day++;
if(snailPosition >= depth){
break;
}
else{
snailPosition -= night;
}
}
console.log(day);
}

Hi Joel!
Considering it's a code coach task, meaning it's common and many had given their attempts for it ... I would suggest you to try and search for similar threads in the forum, and also similar code examples in Code Playground for inspiration on how to "simplify" the code 👍

Thanks it does work
