Given an array of positive integers arr, calculate the sum of all possible odd-length subarrays. A subarray is a contiguous subsequence of the array. Return the sum of all odd-length subarrays of arr. Example 1: Input: arr = [1,4,2,5,3] Output: 58. Explanation: The odd-length subarrays of arr and their sums are: [1] = 1 [4] = 4 [2] = 2 [5] = 5. A subarray is said to be nice subarray if there are k odd numbers on it. So, if the input is like nums = [1,1,2,1,1], k = 3, then the output will be 2 because there are two subarrays [1,1,2,1] and [1,2,1,1]. To solve this, we will follow these steps − odd_i := a new list for i in range 0 to size of nums - 1, do if nums [i] mod 2 is same as 1, then. A subarray of array X[] is a contiguous segment of elements from X[i] through X[j]. where 0 <= i <= j <= n. If the array contains all non-negative numbers, the maximum subarray sum would be the sum of the entire array. Several different sub-arrays may have the same max sum but we need to just return the value of the max subarray sum. Example 1. Lets take an array of size n.There 2 n possible subarrays of this array. Lets take the example array of size 4: [1, 2, 3, 4].There are 2 4 sub arrays..

The time complexity of the above algorithm will be O (N ∗ K) O(N*K) O (N ∗ K), where ‘N’ is the total number of elements in the given array.Is it possible to find a better algorithm than this? A better approach #. If you observe closely, you will realize that to calculate the sum of a contiguous subarray we can utilize the sum of the previous subarray. A naive solution would be to consider all subarrays and, for each subarray , count the total number of 0’s and 1’s present. If the subarray contains an equal number of 0’s and 1’s, update the largest subarray if required. ... Input: T = 1 N = 3 A = [1,0,1] Output: 2 As [1,0] or [0,1] is longest contigous subarray with equal number of 0. In computer science, this means an ordered collection of elements which supports two operations: push appends an element to the end. shift get an element from the beginning, advancing the queue, so that the 2nd element becomes the 1st. Arrays support both operations. In practice we need it very often. Write a java program to read any array and number of queries q each query can be represented by l,r,x print the number of elements less than or equal to x in the subarray represented by l to r. Published on October 26 2017 by Taruni. This problem is mainly a variation of count subarrays with equal number of 0s and 1 s. A naive approach would be to check for all possible subarrays using two loops, whether they are even-odd subarrays or not. This approach will take time. An Efficient approach solves the problem in O (N) time and it is based on following ideas:. Find out the length of the minimum subarray whose sum is greater than or equal to the given number. This question was asked in many product-based companies coding rounds like Goldman Sachs. Example 1: Given array: [3, 1, 7, 1, 2] Given target sum: 11 Output: 3 (Minimum subarray is [3, 1, 7]) Example 2:. You have to count the total number of such subarrays. Input. The first line of input contains an integer T T T denoting the number of test cases. The description of T T T test cases follows. The first line of each test case contains a single integer N N N denoting the size of array. This video explains a very important programming interview problem which is to count the number of subarrays in a given array with sum exactly equals to K. T.
