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
我没有实现时间复杂度为O(n)的算法. 思路:从第一数开始,onelist[0]:onelist[0]+onelist[1]:这样依次推算出每个子数组的sum值.和max进行比较.最后得到max值. 这里需要确定一个起始节点,最开始是onelist[0]为起始节点.一直加到onelist.length. 然后从onelist[1]一直加到onelist.length. import java.util.Scanner; public class Test { public static voi
