Collatz Steps — Edge Case

Node.js Published Updated 0 Views Verified
Node.js Coding Challenge — Collatz Steps (Edge Case). You are building a small JavaScript/Node.js utility. Make the solution safe for empty input, zero, negative values, duplicates or boundary values where applicable. Explain the logic briefly and provide runnable Node.js code. The solution must avoid accidental string-number concatenation and should behave predictably for normal input.

Possible but Incorrect Code

function collatz(n) { const steps=0; while(n!==1){ n=n%2===0?n/2:3*n+1; steps++; } return steps; } console.log(collatz(13));
Additional Explanation
यह option जानबूझकर एक common bug/unsafe approach दिखाता है। इसे production solution के रूप में इस्तेमाल करने से पहले variable scope, async flow, module path, validation, error handling और security checks verify करें। ऊपर दिए गए correct option से exact difference compare करें.

Correct Code / Solution

function collatz(n) { let steps=0; while(n!==1){ n=n%2===0?n/2:3*n+1; steps++; } return steps; } console.log(collatz(13));
Additional Explanation
This solution implements Collatz Steps using standard JavaScript/Node.js syntax. Keep numeric inputs as numbers, validate boundary cases when the problem requires it, and return a value from reusable functions instead of mixing calculation with output.
