the naive iteration approach (Approach 1) may be suitable. If you need to handle arrays of different lengths accurately, Approach 2 provides a solution. Approach 3 using streams offers concise

Given two arrays of integers, we to find the sum of them one array in the reverse using the class and object approach.Example:Input: Input 1st Array : [0]: 10 [1]: 9 [2]: 8 [3]: 7 [4]: 6 [5]: 5 [6]: 4 [7]: 3 [8]: 2 [9]: 1 Input 2nd Array : [0]: 1 [...
Two Arrays and Sum of Functions CodeForces - 1165E,原题链接考察:贪心+思维思路:易知反序和<=乱序和<=正序和.但是这道题是求$f[l,r]$的累加和.我们可以发现由于a是固定的,每个$a[i]$对res的贡献次数也是固定的:即$i*(n-i+1)\(,也就是求\)\sum_1^na[i]*b[i]i(n-i+1)$,因
E. Two Arrays and Sum of Functions(贪心) 题目链接:https://codeforces.com/problemset/problem/1165/E 题目大意: n代表n个数,然后输入a数组,a数组有n个,b数组有n个。然后你可以对b数组里面的数任意排序,最终目的是使得题目中的表达式的值尽可能的小。

We have an array of arrays and are required to write a function that takes in this array and returns a new array that represents the sum of corresponding elements of original array. If the original array is − [ [43, 2, 21], [1, 2, 4, 54], [5, 84, 2], [11, 5, 3, 1...
@zasterI was asking if it was a collection of arrays because you were using array syntax to access the qty/rate properties $sum=$po_item['qty'] *$po_item['rate']; I was assuming they were objects (which is what eloquent returnsunlessyou do ->toArray() on the result. ...
