You have been assigned the task of writing a C function to compute a floating point representation of 2^x. You decide that the best way to do this is to directly construct the IEEE single-precision representation of the result. When x is too small, your routine will return 0.0.When x is too large, it will return +∞. Fill in the blank portions of the code that follows to compute the correct result. Assume the function u2f returns a floating-point value having an identical bit representation as its unsigned argument.
