1.7编写一个算法,若MxN的矩阵中某个元素为0,则将其所在的行与列都清零。 解答:LeetCode上也有这道题。可以用一个长度为M的数组和一个长度为N的数组分别记录有0的行和列。此外也可以利用矩阵本身的存储空间,用其中的一行一列来记录该结果。以下代码基于后一种方法。 1voidsetZero(int**matrix,intm,intn) ...
we cannot access an entire integer in A with a single operation. The elements of A are represented in binary, and the only operation we can use to access them is “fetch the jth bit of A[i]”, which takes constant time. Write code to find the missing...
Leetcode上也有这道题。 1Node * partition(Node *head,intx) {2Node dummy_left(-1), dummy_right(-1);3Node *pl = &dummy_left, *pr = &dummy_right;4for(Node * p = head; p != nullptr; p = p->next) {5if(p->data <x) {6pl->next =p;7pl = pl->next;8}else{9pr->next...
