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 |

@hliu You can try to hit the "run" link and run your submission on ideone.com and see what the runtime error is. Try to use raw_input(), and print functions instead of sys.stdin.readline() It seems to be more efficient. |

I want to solve this problem by Python , but always get 'NZEC', I can't get it. What's the detailed information about 'NZEC'? i handle the input like this: == ca = int(sys.stdin.readline()[0:-1].split()[0]) for i in range(0, ca): lis = sys.stdin.readline()[0:-1].split() ..... is it right?

@Goutam Parashar instead of public class name simply class it will work |

I use VC++ and my program works fine. If I submit compilation is ok but I get runtime error. Why if on VC++ everything is ok and compilation is ok. Something about use to large memory? |

For Java, the submitted file is always run as Main.java, so you can either name your class Main, or you can remove the word public. |

Main.java:6: class Prime_Generator is public, should be declared in a file named Prime_Generator.java public class Prime_Generator { ^ Note: Main.java uses unchecked or unsafe operations. Note: Recompile with -Xlint:unchecked for details. 1 error |
