Min number of operations to reduce N to 0 by subtracting any digits from N | Function to reduce an integer N to Zero in minimum operations by removing digits from N.
Initialise dp [ ] to steps.
Iterate for all elements.
For each digit in number i.
Either select the number or do not select it.
dp [ N ] will give minimum step for N.
Given Number.
Function Call"
How can the above be solved in Python?
