Question

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

var i=1;
while (i<depth)
{
var x=7;
var y=2;
var z=x-y;
var s=z+(7-2);
console.log(s);
i++;
}

}

Answer 1

Declearing variables inside this loop and assigning fixed values will generate the same output, no matter how long the loop.

First don't decleare variables inside the loop, you need two variables, one for days and the other for the distance.

Answer 2

I suggest you to practice making patterns, because they use loops, for example:
*
* *
* * *
* * * *
You can build like these structures using loops.

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

Answer 3

Thank you, hopefully I will practice

Answer 4

True, but I tried declaring the variables outside the loop but still the same error, can you write me the correct solution please?
