Learn essential coding patterns to answer problems and prepare for tech companies' interviews.

Ace the JavaScript Coding Interview

This module teaches us the underlying patterns behind common coding interview questions. By learning these essential patterns, we'll be able to unpack and answer any problem the right way—just by assessing the problem statement. This approach was created by FAANG hiring managers to help us prepare for the typical rounds of interviews at major tech companies like Apple, Google, Meta, Microsoft, and Amazon.

By the end of this module, we'll have the skills we need to unlock even the most challenging questions, grok the coding interview, and level up our career with confidence.

Coding Interview Patterns

# Statement
Given an unsigned 32-bit integer `n`, we need to calculate a 32-bit unsigned integer with reversed bits. When we say “reverse” we don’t mean flipping the $0$s to $1$s and vice versa, but simply reversing the order in which they appear, i.e., from left-to-right to right-to-left.

**Constraints:**

* The input must be a binary string of length $32$
