The current code incorrectly accesses buffer[strlen(buffer)], which points
to the null terminator ('\0') at the end of the string. This is
technically out-of-bounds access since valid string content ends at index
strlen(buffer)-1.
Fix by:
1. Declaring strlen() result variable at function scope
2. Adding bounds check (len > 0) to handle empty strings
3. Using buffer[len-1] to correctly access the last character before
the null terminator
