#2932-bit Status Code Converter

You are developing a system diagnostics tool that receives a 32-bit status value generated by a computer system. For easier debugging, the diagnostic tool must display the value in its hexadecimal representation. Given a signed 32-bit integer statusCode, return its hexadecimal representation as a lowercase string.

Rules:

• Use lowercase hexadecimal characters (0-9 and a-f).
• Do not include leading zeros.
• The value 0 must be represented as "0".
• For negative values, use the 32-bit two's-complement representation.
• You cannot use a built-in function that directly converts an integer to hexadecimal.
• The conversion must be performed using bitwise operations or equivalent arithmetic logic.
