PRIME1  Prime Generator
Peter wants to generate some prime numbers for his cryptosystem. Help him! Your task is to generate all prime numbers between two given numbers!
Input
The input begins with the number t of test cases in a single line (t<=10). In each of the next t lines there are two numbers m and n (1 <= m <= n <= 1000000000, nm<=100000) separated by a space.
Output
For every test case print all prime numbers p such that m <= p <= n, one number per line, test cases separated by an empty line.
Example
Input: 2 1 10 3 5 Output: 2 3 5 7 3 5Warning: large Input/Output data, be careful with certain languages (though most should be OK if the algorithm is well designed)
Information
After cluster change, please consider PRINT as a more challenging problem.hide comments

use trial division method. Run the loop till sqrt of n. No need to use any kind of Sieves for this simple problem.

when i am running my code in other IDE... my code is correct and giving the correct output but when i submit it here it is displaying time limit exceeded .

i used Fermat's primality test algorithm which takes O(k*log(n)) to check whether a number is prime or not.

Do we have an editorial section on spoj

AS SOON AS THE VALUE OF COUNTER IS MORE THAN 1,COME OUT OF LOOP,AC IN ONE GO....THANK ME LATER

using the usual prime number code with square root will give u the answer.
