Practice Question: ​Example Question?

Reveal Solution

An unsigned int-32 would have all 32 bits to represent its value, but we need to remember to subtract one because one combination of bits is used to represent 0. Therefore the max value of a uint-32 is 2^32-1. But I asked for a signed int-32 which requires the first bit to represent the sign. Therefore the max value of a uint-32 is 2^31-1.
