INTEST - Enormous Input Test |
The purpose of this problem is to verify whether the method you are using to read input data is sufficiently fast to handle problems branded with the enormous Input/Output warning. You are expected to be able to process at least 2.5MB of input data per second at runtime.
Input
The input begins with two positive integers n k (n, k<=107). The next n lines of input contain one positive integer ti, not greater than 109, each.
Output
Write a single integer to output, denoting how many integers ti are divisible by k.
Example
Input: 7 3 1 51 966369 7 9 999996 11 Output: 4

0.09 seconds with getchar_unlocked. Do you have any "more efficient algorithm" ? |

Use ios_base::sync_with_stdio(false), solved in 0.5 |

Fastest I could get with PyPy was 0.93 seconds - tried every variation of standard in that I could think of. |

Submitted in python 2.7.10 got TLE, resubmitted same solution in Pypy got AC in 1.02 seconds. |

Is there any other tricks other than getchar_unlocked in c?? |

0.11s with getchar_unlocked and .56 with scanf . stream input output functions take time around 5s here. |
