Hi this is one of the first problems I've done and for some reason, I got the error NZEC. Could someone explain what it means and why I got it. Here is my code, it is submission number 728302.
num=input()
for z in range():
a=raw_input()
x=int(a)+1
while a:
a=str(x)
if a==a[::-1]:
print a
break
else:
x=x+1
Please help I've tried everything but it won't go through.
