Find the kth largest element in an unsorted array. Note that it is the kth largest element in the sorted order, not the kth distinct element. For example, Given [3,2,1,5,6,4] and k = 2, return 5. Note: You may assume k is always valid, 1 ≤ k ≤ array'

设子数组A[0:k]和A[k+1:N-1]已排好序(0≤K≤N-1).试设计一个合并这2个子数组为排好序的数组A[0:N-1]的算法.要求算法在最坏情况下所用的计算时间为O(N),只用到O(1)的辅助空间. //翻转字符串时间复杂度O(to - from) void reverse(int *a, int from, int to) { int t; for (; from < to; ++from, --to) { t = a[from]; a[from] = a[to]; a[to] = t
