In this post, we will see how to generate all subarrays of given array. Problem Print all print all subarrays of given array. For example: If array is {1,2,3} then you need to print {1}, {2}, {3}, {1,2}, {2,3}, {1,2,3} Solution If there are n elements in the arr...
arr[i]is part of sub-array [1,2,3] but not part of [1] or [1, 2] (both starting from 1 which is part of preceded elements). Now the question is of how many subarrays of any preceded element,arr[i]is part of. Answer is(n-i)as subarray containing arr[i](starting from any...

I have been trying to solve a problem where i needed to find the sum of the minimum of all the subarrays of an array. If someone know of an O(N) algorithm to such problem. Thanks.+7 Hamada14 8 years ago 18 Comments (16) Show archived | Write comment? _index 8 years ago,...
If we take a close look then we observe a pattern. Let take an example arr[] = [1, 2, 3], n = 3 All subarrays : [1], [1, 2], [1, 2, 3], [2], [2, 3], [3] here first element 'arr[0]' appears 3 times
