Objective

Implement a function that flips a null-terminated string end-to-end, modifying the original buffer, then hands the same pointer back to the caller.

Steps

• Your function receives a single char * argument pointing to a mutable buffer.
• Swap characters from both ends, moving inward, until the two indices meet or cross.
• Do not allocate any extra memory, the reversal must happen inside the buffer that was passed in.
• Return the original pointer unchanged after the in-place swap is complete.
