WebbP - Mex. Submissions Submit. Ali has an array of n distinct numbers. He wants to calculate the sum of F (L, R), where F (L, R) is the mex of the numbers in the subarray [L, R] (0 <= L <= R <= n-1). Knowing that the mex of an array is the minimum excluded number (mex (1,2) = 0, mex (0,1,2)= 3). Can you help Ali to find the sum of F (L, R) for ... Webb15 juni 2024 · Simple Approach: The simple approach to solve this problem is to run two for loops and for every subarray check if it is the maximum sum possible. Follow the below steps to solve the problem. Run a loop for i from 0 to n – 1, where n is the size of the array. Now, we will run a nested loop for j from i to n – 1 and add the value of the ...

WebbCheck if a particular subarray sum is at least k. If so try to update the shortest possible length of subarray with sum >= K. For checking sum of a subarray, you can use can create a prefix sum array, and get sum in constant time. But it will require extra space O(N). But instead, we can store sum as we iterate through our subarray.
