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...
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 ...
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...
Learn how to find all subarrays of a given array in Java with this comprehensive guide, including examples and explanations.
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...
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

Step 3 ? Once a for loop is used to prepend every string array element, the resultant array with its length property is returned because the prepending new string array replaces the original string array given as input by the user. Example Below is an example of prepending a string into a...
828. Count Unique Characters of All Substrings of a Given String # 题目 # Let’s define a function countUniqueChars(s) that returns the number of unique characters on s, for example if s = "LEETCODE" then "L", "T","C","O","D" are the unique characters
