Note:You may assume that A has enough space (size that is greater or equal tom+n) to hold additional elements from B. The number of elements initialized in A and B aremandnrespectively. 解法一:从前往后,小的排最前。每次插入一个B,A需要整体后移。 classSolution {public:voidmerge(intA[],i...
到这里我们就明白了为何要使用 nums1[:]。这里 sorted() 函数返回的必然是一个新的对象,因此我们需要 nums1[:], 而 [] 也代表一个新的 list 对象,我们需要用 nums1[:] = []。 ps: 如果没有就地修改的要求,则用 nums1 也是完全正确的。 因此对思路一进行代码修改,顺利通过 1 class Solution: 2 def...

Mergenums1 and nums2 into a single array sorted innon-decreasing order. The final sorted array should not be returned by the function, but instead be _stored inside the array _nums1. To accommodate this, nums1 has a length of m + n, where the first m elements denote the elements...
按照归并排序的惯性思路,因为归并排序中给定的是一个数组的两个区间,所以通常情况下会借助O(n)大小的辅助空间。思路如下: class Solution { public: void merge(int A[], int m, int B[], int n) { int temp[m+n]; int i = 0, j = 0, t = 0; ...
Write a C program to merge two sorted array elements into a single array. Problem Solution 1. Create two arrays of some fixed size and define their elements in sorted fashion. 2. Take two variables i and j, which will be at the 0th position of these two arrays. ...
Sample Solution:C Code:#include <stdio.h> int main() { int arr1[100], arr2[100], arr3[200]; int s1, s2, s3; int i, j, k; printf("\n\nMerge two arrays of same size sorted in decending order.\n"); printf("---\n"); printf("Input the number of elements to be stored ...
www.lintcode.com/en/problem/merge-sorted-array/ 【题目解析】 直观思路显然是双指针i, j同时扫描A, B,选min(A[i], B[j])作为下一个元素插入。但是只能利用A后面的空间来插入,这样就很不方便了。 反向思路,merge后的数组一共有m+n个数。i, j从A, B尾部扫描,选max(A[i], B[j])插入从m+n起...
