Minimum pair merge operations required to make Array non | Function to find the minimum operations to make the array Non - increasing.
Size of the array.
Dp table initialization.
dp [ i ] : Stores minimum number of operations required to make subarray { A [ i ] , ... , A [ N ] } non - increasing.
Increment the value of j.
Add current value to sum.
Update the dp tables.
Return the answer.
Driver Code"
How can the above be solved in Python?
 ... Write me a code to minimum pair merge operations required to make Array non and the other steps required?
