Description Every year the cows hold an event featuring a peculiar version of hopscotch that involves carefully jumping from rock to rock in a river. The excitement takes place on a long, straight river with a rock at the start and another rock at th

1.选择排序: //改进后的选择排序,减少交换的次数 public static void sortSelect(int arr[]) { //用于存放最小数的下标 int s; for (int i = 0; i < arr.length; i++) { s = i; for (int j = i + 1; j < arr.length; j++) { if (arr[s] > arr[j]) { //记录最小值的下标值 s = j; } } //如果最小数的下标值改变,则交换 if
搜索的应用-计算最优解 题目: You are given nn packages of wiwi kg from a belt conveyor in order (i=0,1,...n−1i=0,1,...n−1). You should load all packages onto kk trucks which have the common maximum load PP. Each truck can load consecutive packages (more than or e
题目:在翻转有序中搜索 难度:Medium 题目内容: Suppose an array sorted in ascending order is rotated at some pivot unknown to you beforehand. (i.e., [0,1,2,4,5,6,7] might become [4,5,6,7,0,1,2]). You are given a target value to search. If found in the array return its
