Multiply 2 numbers using recursion

#1

i wrote code for this and its working fine but i want to know if there can be some optimisations
if there are any optimisation plz explain them

my code: https://ide.codingblocks.com/s/85740

#2

this is correct.
optimization to recursion can be done by memoization and dynamic programming (top down or bottom up approach)

#3

whats memorization and dp ?
we will learn that in further course …then we can do that
bcz dp is not taught yet

#4

yes it will be taught in the coming content of the course
wait for it after learning dp you will be able to do that
