//your code goes h
climb = 0;
for(var days=1;;days++){
climb+=7;
if(climb>=depth){
break;

}

console.log(days);

Answer 1

//Try this

function main() {
var depth = parseInt(readLine(), 10);
console.log(Math.ceil((depth-2)/5))
}

Answer 2

mistake in for loop :
1. for ([initialExpression]; [conditionExpression]; [incrementExpression])

where is your condition

2. Call the function main()

Answer 3

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);

}
