- * A utility class for performing single-bit operations on integers.
- * These operations include flipping, setting, clearing, and getting
- * individual bits at specified positions.
- *
- * Bit positions are zero-indexed (i.e., the least significant bit is at position 0).
- * These methods leverage bitwise operations for optimal performance.
- *
- * Examples:
- * - `flipBit(3, 1)` flips the bit at index 1 in binary `11` (result: `1`).
- * - `setBit(4, 0)` sets the bit at index 0 in `100` (result: `101` or 5).
- * - `clearBit(7, 1)` clears the bit at index 1 in `111` (result: `101` or 5).
- * - `getBit(6, 0)` checks if the least significant bit is set (result: `0`).
- *
- * Time Complexity: O(1) for all operations.
