I am using Python 2.6
I have modified that code
def main():
t=int(raw_input())
while(t):
x=input()
print str(etf(x))
t-=1
what should i do to handle new line and space......
We used to get spaces and newline in C using their ASCII values ...can
similar things be done here???
Please write the code snippet(by modifying my code) from which i can
understand something......!!!!!
