Why is my Function returning 1 when I expected it to return 4?

Question

function main() {
var depth = parseInt(10);
var days = 0;
for (var i = 0; i < 20; i++) {
depth = depth + 7;
days = days + 1;
if (depth = 32) {
break;
}
else {
depth = depth - 2;
}

}
return days;
}
var abc = main();
console.log(abc);

Answer 1

Change the condition to:

if (depth == 32)

"=" is the assignment operator while "==" compares two values.

Answer 2

Thank you! I keep making this mistake again & again.......

Answer 3

I immediately see two errors:
1. you do not need to add the number of days +1 in the loop. the variable "i" is already a day counter.
2. don't be hard-wired to the number of days 32. this is not a constant. this is a variable that the test automatically enters itself when checking and this is the depth variable

Answer 4

Hi! Are you trying to solve the snail in the well problem?

Try this you will got your mistake:

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

}
console.log(day);
}

Happy coding 🤘
