You are not alone, read it again!Did you mean: recursion //A google easter egg for recursionClick here : https://www.google.com/search?q=recursionThe process in which a function calls itself directly or indirectly
is called recursion.
// Recursive Addition
f(n) = 1 n = 1
f(n) = n + f(n-1) n > 1Looking for the meaning of recursion ?

# Memoization
# Memoization is often useful in recursion. This is when the results of a function call are remembered so they can be used again in later function calls. This is like caching your results to use again.
# Code Example
factorial_memo = {}
def factorial(n):
if n <= 1:
return 1
elif n not in factorial_memo:
factorial_memo[n] = n * factorial(n-1)
return factorial_memo[n]
# Tail Recursion
# Tail recursion is where calculations are performed first and then the recursive call is executed. Some programming languages, usually functional ones, optimize tail calls so they take up less room on the call stack.
