Example 1: Simple Array Summation Let’s start with a straightforward example: array=[1,2,3,4,5];totalSum=sum(array);disp(totalSum); Here, we start with the basic task of finding the sum of elements in a one-dimensional array. The array[1, 2, 3, 4, 5]is defined, and thesumfu...
高效方法:计算sum_array 是使用滑动窗口的概念,因此可以轻松节省我们的时间。对于滑动窗口,时间复杂度为 O(n)。算法 calculate sum of first (m/2)+1 elementssum_array[0] = sumfor i=1 to i= 0 ) sum -= arr[(i-(m/2)-1)]if( (i+m/2) < n) sum += arr[(i+m/2)]sum_array[i] ...
