📚 Bit Counting Algorithms

Brian Kernighan's Algorithm n = n & (n - 1) removes the lowest set bit

O(number of set bits) - Most efficient!

Naive Loop Check each bit: (n >> i) & 1

O(log n) - Checks all bit positions

Built-in Popcount __builtin_popcount(n) or Integer.bitCount(n)

O(1) - Hardware instruction
