If you want to practice data structure and algorithm programs, you can go through100+ data structure and algorithm programs. 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} ...
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...
Can we find Bitwise And of all subarrays of an array in O(n) time ? If not,then what is the best time complexity for doing this ?-26 that_wasnt_me 6 years ago 6 Comments (1) Show archived | Write comment? JohnWright 6 years ago, # | +26 This question is from ...
// sum subarray between current // starting and ending points for(intk = i; k <= j; k++) result += arr[k] ; } } returnresult ; } 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], ...
Can someone explain the optimal solution for finding the sum of XOR of all sub-arrays of the array. Example: Input : arr[] = {3, 8, 13} Output : 46 XOR of {3} = 3 XOR of {3, 8} = 11 XOR of {3, 8, 13} = 6 XOR of {8} = 8 XOR of {8, 13} = 5 XOR of {13...
