https://leetcode.com/problems/product-of-array-except-self/ 去掉限制条件的话非常水。 但是题目要求不能用除法,线性时间复杂度,常数的空间复杂度,这也不行那也不行真是任性。 解法是构造两个数组,第一轮遍历累乘左边的值,第二轮遍历累乘右边的值。 比如:[3, 4, 5, 6] 累乘左,第一个是1:[1, 3, ...
Find Minimum in Rotated Sorted Array Suppose a sorted array is rotated at some pivot unknown to you beforehand. (i.e.,0 1 2 4 5 6 7might become4 5 6 7 0 1 2). Find the minimum element. You may assume no duplicate exists in the array. https://leetcode.com/problems/find-minimu...
for(int i=0;i<len;i++){print(nums[i]);} 原题链接:https://leetcode-cn.com/problems/remove-duplicates-from-sorted-array 思路解析 + 在必须原地修改输入数组的限定条件下,我们的思路就是不断地将数组的后部向前部挪动。因为是排好序的数组,所以重复的数字必然连着出现。为了消除重复,每次挪动只需要让...
