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, n-m<=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.| Added by: | Adam Dzedzej |

@ysn - It's far simple than Topcoder. You simply have to make a program which takes 't' that is number of test cases as input then take input for each test case which will be of form 'm' and 'n' then you have to print prime numbers from m to n (inclusive). Do not forget to print each prime in newline. I am still struggling how to work in Topcoder arena. :-| |

i migrated from Topcoder and project euler. on Topcoder, you just write your code and declare the variables as indicated. but here i think its diffrent; the input is in lines not simply an array, int,String... as Topcoder. so how am i supposed to make my code to accept the inputs? by a scan method? |

what is the reason of runtime error that normal which we all are getting |
