nCr (Binomial Coefficient) Dry Run in PYTHON

nCr (Binomial Coefficient) is an interactive PYTHON dry run visualizer from the Recursion programs section. Study the source code, then use the execution controls to follow each step, variable update, highlighted line, and console output.

This page provides a browser-based dry run with source-code highlighting, auto-scroll, voice narration controls, and execution output for learning the program step by step.

nCr (Binomial Coefficient) Program Code

def nCr(n, r):
    if r == 0 or r == n:
        return 1
    if r > n:
        return 0
    return nCr(n-1, r-1) + nCr(n-1, r)

n, r = 5, 2
print(f"C({n},{r}) = {nCr(n, r)}")
