Can you provide a code to longest remaining array of distinct elements possible after repeated removal of maximum and minimum elements of triplets and the other steps required given the following:
Longest remaining array of distinct elements possible after repeated removal of maximum and minimum elements of triplets | Function to return length of longest remaining array of pairwise distinct array possible by removing triplets.
Stores the frequency of array elements.
Traverse the array.
Iterate through the map.
If frequency of current element is even.
Stores the required count of unique elements remaining.
If count is odd.
Driver Code"
How can the above be solved in Python?
