Shorter recursive :)


def GCD(a, b):
return a if b==0 else GCD(b, a%b)

[EintsWaveX]

Shorter codes:
1. Sum of n[s] = return int(n * (n + 1) / 2)
2. GCD = if m == 0: return n; return gcd(m, n % m)
3. LCM = prod = n * m; hcf = gcd(n, m); return int(prod / hcf)
Thanks :)

while 1:

Your "gcd" program assumes b>a. Which is not necessarily the case every time. This was a great introduction but lacking corner case checks.

[ovoydas]

We are not here to see what you are doing !! Make us understand the whole code.

[harishkatariya]

Suggest some practice books for python competitive programming

[KrishnaGupta-ngtv]

Please also do it in C++ as C++ is bit faster than python...Just open a file in which c++ code is written and explain the code via comparison with python. It would take just extra 2 minutes only..
Thanks for this series too....

Sir is it necessary to write the codes exactly as u mentioned. Can we write it in our own way if it gives correct result and logically correct as well ?

[KrishnaManohar]

hello Django boy hpy to see u in this series. I am not happy with your Django series try to push up the speed.
