Hi. What exactly is the problem with the while loop?

I think there is some criteria for minimum honor to unlock solution section without solving it, so you have to solve more problems and unlock that button.

Already answered in your other post, the problem was you used elsif there:

elsif

ns = 0 # this is line 7

There it was your = in a conditional
The current code works (see how you use proper markdown so your code doesn't lose indentation and such).

I added my whole solution code.

1. This is not a bug, but issue with your code
2. Yes, you can leave your solution under a spoiler tag if you need some help.
3. You are not providing your whole code. You excluded beginning and end of the function (though when you asked this question on forum you posted the whole code, not part of it), because of this we can see a correct loop, but we can't see your elsif right before the loop which has no condition to be tested on.

Also here it can't be marked as containing spoilers.

elsif

ns = 0 # this is line 7

There it is your = in a conditional

Is this a bug?

This is asking a wrong question in a wrong place...

I've met a problem in Kata 'Take a Ten Minute Walk' - http://www.codewars.com/kata/take-a-ten-minute-walk/train/ruby

My code:

def isValidWalk(walk)
if walk.length!=10
return false
elsif
ns = 0
ew = 0
for i in 0..walk.length-1 do
if walk[i]=='n'
ns=ns+1
elsif walk[i]=='s'
ns=ns-1
elsif walk[i]=='e'
ew=ew+1
elsif walk[i]=='w'
ew=ew-1
end
i+=1
end

if ns==0 && ew==0
  return true
else
  return false
end

end
end

All tests passed correctly, but the system tells me about an Error:

STDERR:

main.rb:7: warning: found = in conditional, should be ==

But the string #7 is: for i in 0..walk.length-1 do
It does not contain symbol '='...

Is this a bug?
