Depth

Question

Help plz

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.

Sorry to say buddy, but your code is all over the place.

You have set up 2 vars count & days. Maybe rename count to climb for clarity.

Also, we don't know how many times we need to iterate because we don't know how deep the well is, so let's use a while loop.

The logic of the code is:

while the climb is <= depth
the snail must climb +=7 feet
this takes += 1 day
if the snail has climbed high enough, break the loop
else the snail must rest and slips down the climb -= 2 feet
next day this sequence repeats.

When the loop is broken
print the days

Simple declear two variables amd store 7-2 result in any of one Variable like this

var a
var b=7-2;
Herr in first day you need to multiple by i set i =0 then value will be like this value =i *5 +b

Then second day u need to increment value of i use while loop here now this time i will be 1 so
1*5+ b
Same for day 3

2*5+b
....

....
....
6 th day
5*5+b
Your problem solved

Can you attach your code for us to look at.
It makes it easier to assist you if we can see your concept

Answer 4

I already got the loop that I'm supposed to use to get the values within the range of the given depth....but I can't seem to be able to get the day before the depth or even the depth position between the days

Answer 5

Here's my code....

fun main(args: Array<String>) {
depth(31)
}
fun depth(depth:Int){
var count=0
var days=0

for(i in count..depth){
count+=7-2
days+=1
if(count<=depth){
println("$days day: $count")
}else{
break
}
}
println ("::::::")
println("$days, days to get out")
}
