Test case 4: The array could be [1, 0, 3, 2]. It means that there doesnt exists any subarray where x is present. You switched accounts on another tab or window.

M's submission of Subarray Mex | CodeChef The second line contains N space-separated integers A1, A2, , AN denoting the array A. TheMEX(minimum excluded) of an array is the smallest non-negative integer that does not belong to the array. Since subarrays are part of array it means that there shouldnt exist integer x in array A. You will soon realize that one of the ways is to have A_i = A_{i-K}. Tester: Manan Grover Maximum Subarray - LeetCode discus throw codechef solution: 2: bath in winters codechef solution: 3: count the ones codechef solution: 4: mex on trees codechef solution: 5: subarray xor codechef solution: 6: substring of a substring codechef solution: 7: exact marks codechef solution: 8: akash and function codechef solution: 9: akash and missing class codechef slution: 10 . One of the ways is to choose all the values from 0 to K (inclusive) except X. In particular, an array is a subarray of itself. So the maximum MEX, that any subarray can have is m. Now, lets move towards Dynamic Programming. What is the meaning of dp[i], pre_dp[i], next_occ[i]? If the count becomes equal to M, we have found the permutation. Test case 4: The array could be [1, 0, 3, 2]. Input: Share your suggestions to enhance the article. Since MEX of array is m, it means that all integers less than m exists in array.

Test case 4: It is optimal to take the subarray [2,3] and the bitwise AND of 2 and 3 is 2. Hi @cherry0697, can you help me with this submission, i am unable to find a test case where it fails. We can see that adding A_1 to this set will obviously make the MEX of the set to be X.
