int s1) { static int result[2]; // Static array to store the sum of even and odd numbers for(int i = 0; i <= s1; i++) // Loop through the array
We have an arrayAof integers, and an arrayqueriesof queries. For thei-th queryval = queries[i][0], index = queries[i][1], we add val toA[index]. Then, the answer to thei-th query is the sum of the even values ofA. (Here, the givenindex = queries[i][1]is a 0-based ind...
Can you solve this real interview question? Sum of Even Numbers After Queries - You are given an integer array nums and an array queries where queries[i] = [vali, indexi]. For each query i, first, apply nums[indexi] = nums[indexi] + vali, then print the
printf("Sum of even numbers from 1 to 100: %d\n", sum); return 0;} 1. **问题分析**:目标是计算1到100之间所有偶数的和。 2. **数学推导**:偶数的范围是2到100,每隔2递增,构成等差数列。求和公式为:**S = n * (a1 + an) / 2** - 项数n = 50(2到100共50项), a1=2, an=100...
