lst=[]        
a=int(input())
for i in range(a):
    b=int(input())
    c=input()
    lst.append(c)
for i in lst:        
    ans=checkempty(i)
    if(ans):
        print("YES")
    else:
        print("NO")

For the given test cases this code was running fine but when i submmited the submission was unsuccessful. can someone tell what is the error in the logic??

I am providing link of my solution just take outputs of random input then try to debug. I think debugging your own solution is a way to improve
here is linkEventual

Hello @rahul10398, explain your code/approach so that everyone can understand. Btw, this is my solution. it’s the same approach I guess. Feel free to ask if anything is unclear.

i figured out the error. actually i was returing true inside for loop in checkcount function. when i corrected it test cases passed. silly mistake
