WebYour task is to complete the function kthSmallest () which takes the array arr [], integers l and r denoting the starting and ending index of the array and an integer K as input and returns Find maximum (or minimum) sum of a subarray Performance: The above solution does 2 (n-1) comparisons in the best case and 3 (n-1) comparisons in the worst case. The idea is based on the approach discussed in next greater element article. So, the sum will be ((j i +1)*(j i +2))/2. We start i from 0 and j from n-1. We dont actually need dp( i, 3), if we update dp(i, 1) as max(dp(i, 1), dp(i-1, 1)) and dp(i, 2) as max(dp(i, 2), dp(i-1, 2)).Thus, dp(i, j) is the maximum total sum of the elements that are selected if the last element was taken from the position (i-1, 1) or less. Our answer in this case will be 1 + f(i+1, j). Thank you for your valuable feedback! This article is being improved by another user right now. Minimum number of increment-other operations to make all array elements equal. Return the maximum of prev1 and prev2 as the maximum sum combination from the two arrays. 1. Similarly, iterating from MSB to LSB (32 to 1) for bit position we can easily check which bit will be part of our solution and will keep adding all such bits to our solution. Below is an implementation of the above idea. 1. Your task is to find the sum of minimum and maximum element in the array. Step 2: Now we traverse the array and pick elements in pairs.
