Snail in the well problem

Question

can someone tell me why this isn't working:

function main() {
var depth = parseInt(readLine(), 10);
var rem = depth % 5;

switch(rem) {
case 0:
console.log((depth-rem)/5);
break;
case 2:
console.log((depth-rem)/5);
break;
case 1:
console.log(((depth-rem)/5)+1);
break;
case 3:
console.log(((depth-rem)/5)+1);
break;
case 4:
console.log(((depth-rem)/5)+1);
break;

}

//i'm getting one test case not working

Answer 1

You are overcomplicating this problem... It could be solved as easy as something like that:

function main() {
var depth = parseInt(readLine(), 10);
//your code goes her
var days = 0;
while (depth > 0){
days += 1;
depth -= 7;
if (depth <= 0)
break;
depth+= 2;
}
console.log(days)
}

Answer 3

case 1:
console.log((depth-rem)/5);
break;

Answer 4

Very Simple
Take a look:

function main() {
var depth = parseInt(readLine(), 10);
//your code goes here
var day=0;
var i;
for( i=0; day < depth; i++)
{
day += 7;
if(day >= depth)
{
i += 1;
break;
}
day -= 2;
}
console.log(i);

}
