Optimised sieve AC in one go.... :

optimised seive:)

sieve of eratosthenes gives AC in 0.93s (with printf)

good question!!
runtime on ideone but AC on spoj..
Thanks _maverick for your comment

sieve -> AC in 9.36,, Phew!

@ALL people who solved it in under 4 seconds. How?! A hint at least!
My implementation of sieve (using only 1 or 5 mod 6 numbers) as a bool array takes 9.xx seconds and bitwise sieve of integers takes 7.xx seconds. How to optimize further?

Update: 6.62 s after using Atkin. :/

We can easily bring this under 1 sec, just lil coding needed.i wish the timelimit was under 2 seconds. Would have been much more fun.lazy i m .

optimized sieve+putchar_unlocked()->AC :)

@surayans tiwari IDEONE is using **CUBE** cluster and here SPOJ is using Pyramid cluster...CUBE id 20X faster than Pyramid.

running in 1.7 seconds on ideone and tle here please check my code
