Problem 1.4 Fill in one line of C expression in the "return" statements of the two functions below that implements the function. Your code should conform to the rules below. Each expression should use ONLY the following: 1. Integer constants 0 through 255 (0xff), inclusive. You are not allowed to use big constants such as Oxffff. 2. Function arguments and local variables (no global variables). 3. Unary integer operations ! 4. Binary integer operations ^ | + * return -X * negate - *Example: negate (1) * int negate (int x) { } return * tmax return maximum two's complement integer * int tmax (void) { } = - 1. return
