Find sum of all subarrays
WebSuppose arr is an integer array of size N (arr[N] ), the task is to write the C program to find the sum of all sub-array sum for a given array. Method 1: By Generating sub array. This method is very simple to calculate the sum of sub-array, in which we will just list off all the subarrays and add all of them up. WebMay 29, 2024 · 6. A contiguous subarray is simply a subarray of an array with a condition that the elements of the subarray should be in exact sequence as the sequence of the elements in the array. for example if the array is [1,2,3,4,5] then [1,3,5] is a subarray of the array, but not a contiguous subarray since the sequence does not match as the …

Our task is to create a program to find the sum of XOR of all subarrays of the array. Here, we need to find all sub-arrays of the given array, and then for each subarray, we will find the xor of element and add the XOR value to the sum variable.
WebUsing sum () with generator expressions this can be shortened to. def subarray_sum (a): n = len (a) total = sum (sum (sum (a [i:j + 1]) * a [j] for j in range (i, n)) for i in range (n)) … WebOct 16, 2024 · You need to find the maximum sum of a subarray among all subarrays of that array. A subarray of array A[] of length n is a contiguous segment from A[i] through A[j] where 0<= i <= j <= n. Some properties of this problem are: If the array contains all non-negative numbers, the maximum subarray is the entire array.
