Number of subarrays with maximum values in given range Medium Accuracy: 16.67% Submissions: 6 Points: 4 Given an array of N elements and L and R, print the number of sub-arrays such that the value of the maximum array element in that subarray is at least L and at most R. Following program implements the simple solution. See below set 2. edit Given an unsorted array A of size N that contains only non-negative integers, find a continuous sub-array which adds to a given number S.. How do I print the numbers whose sum is equal to the maximum sum. A bitonic subarray is a subarray in which elements are first increasing and then decreasing. Get hold of all the important DSA concepts with the DSA Self Paced Course at a student-friendly price and become industry ready. Yes, it is possible to do it in O(n log n) time.. Let's take a look at prefix sums. Efficient Approach: There is an idea if all the elements of the array are positive. It contains well written, well thought and well explained computer science and programming articles, quizzes and practice/competitive programming/company interview … Create a hash table that holds the count of each sum[i] value, where sum[i] = sum(arr[0]+..+arr[i]), for i = 0 to n-1. Expected Auxiliary Space: O(N). Formally, the task is to find indices and with ≤ ≤ ≤, such that the sum ∑ = [] is as large as possible.
