What is a code to maximize the number of indices such that element is greater than element to its left and the other steps required given the following:
Maximize the number of indices such that element is greater than element to its left | Function to find the maximum pairs such that arr [ i + 1 ] > arr [ i ].
To store the frequency of the element in arr [ ].
Store the frequency in map M.
To find the maximum frequency store in map M.
Print the maximum number of possible pairs.
Driver Code"
How can the above be solved in Python?
