ABCDEF - ABCDEF
You are given a set S of integers between -30000 and 30000 (inclusive).
Find the total number of sextuples that satisfy:
Input
The first line contains integer N (1 ≤ N ≤ 100), the size of a set S.
Elements of S are given in the next N lines, one integer per line. Given numbers will be distinct.
Output
Output the total number of plausible sextuples.
Examples
Input: 1 1 Output: 1 |
Input: 2 2 3 Output: 4 |
Input: 2 -1 1 Output: 24 |
Input: 3 5 7 10 Output: 10 |

Use Vector instead of Array. Sort() of STL instead of qsort. Use upper_bound() & lower_bound() instead of Binary Search & Linear Search. Use scanf instead of cin for faster I/O. Finally AC after 5 TLE's. :( |

upper_bound, lower_bound / binary search and d!=0. |
