3) it must be minimum possible number. Answer (1 of 3): The essence of the algorithm used by a sieve is removing the factors of the number. Registered members Current visitors New profile posts Search profile posts. Originally Answered: What is the solution to PRIME1 on SPOJ? You need to make it faster - for test cases such as the range 999900000-1000000000, Eratosthene's sieve algorithm is too slow. In each of the next t lines there are two numbers m and n (1 <= m <= n <= 1000000000, n-m<=100000) separated by a space. What is the function of in ? while 1: a, b, c = [int(x) for x in raw_input().split()] if a == 0 and b == 0 and c == 0: break elif b - a == c - b: print 'AP', c + (b - a) elif b/a == c/b: print 'GP', c * (b/a) # end of source code Be Pythonic.
