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 |

This may be the dumbest question ever asked on here.. I know I can figure out how to print all the prime numbers, but i'm not sure how to actually read the input into my Javascript function? Do I just use readline(); and the input comes through as an array that I can save into a variable? for example, var data = readline(); and now the input is saved into the variable data as the array [2, [1, 10], [3, 5]]? or does the input come through as text that I need to split? or do I need to do it some other way? |

AC in one Go. :) Use Segmented Sieve Concept with slight Logical change. |

@priyanka_2: Use sieve algorithm. |

You don't need a vector! |
