http://codeforces.com/contest/802/submission/137971347 [AGC056D] Subset Sum Game 这种题的套路大概是 Alice 先选定一种匹配并取走一对匹配中的一个元素,然后 Bob 可以在剩下的匹配中每组取走一个,如果无论如何留给 Alice 的元素都能满足条件那么 Alice 赢,否则若不存在这种匹配那么 Bob 赢。于是可以枚举 Al...
heapify - create a heap from an array of elements, needed for heap_sort heap_sort() - take an unsorted array and turn it into a sorted array in-place using a max heap or min heap Sorting Notes: Implement sorts & know best case/worst case, average complexity of each: no bubble sort...
CodeForces 1095B Array Stabilization You are given an arrayaa consisting ofnn integer numbers. Letinstability of the array be the following value:maxi=1nai−mini=1naimaxi=1nai−mini=1nai . You have to removeexactly one element from this array to minimizeinstability of the resulting(n−1...
