#331 Reverse Bits

Given a 32-bit unsigned integer, reverse its bits and return the resulting number.

Rules:

• Input is a 32-bit unsigned integer
• Must reverse all bits (including leading zeros)
• Return the decimal value of reversed bits

Examples:

// Example 1:

console.log(reverseBits(0b00000000000000000000000000010101));
// Output: 2818572288

// Explanation: 

// Input:  00000000000000000000000000010101

// Output: 10101000000000000000000000000000

// (decimal representation: 2818572288)


// Note: In JavaScript, you'll receive and return regular numbers,

// but they represent 32-bit unsigned integers

Note: JavaScript doesn't have native unsigned integers, but for this problem:

• Input will be a valid 32-bit unsigned integer
• Output should be treated as unsigned 32-bit integer
