### Feedback

I wanted to know the reason why my code fails in submission.It works for all test custom inputs with the correct result which is aimed for in the question.

Question:

Zero Ones Equal One Zeros

My code:

for i in range(int(input())):

n=int(input())

a=“010”

b=“1001”

odd=‘10’

even=‘01’

if n==3:

print(a)

elif n==4:

print(b)

elif n%2==0 and n>4:

c=n-4

print(str(b+str((c//2)*even)))

elif n%2!=0 and n>3:

c=n-3

print(str(a+str((c//2)*odd)))
