📚 Toggle the ith Bit

To toggle (flip) the ith bit of a number, use XOR with a mask:

          result = n ^ (1 << i)

          // XOR Truth Table:

          // 0 ^ 1 = 1 (turns ON)

          // 1 ^ 1 = 0 (turns OFF)

          // Example: Toggle bit 2 of 85 (01010101)

          // 1 << 2 = 00000100

          // XOR -----------

          // 81 = 01010001

XOR with 1 always flips the bit. This is perfect for toggles!
