The digital hardness of an integer is measured by examining its representation in binary (base 2). Working from the ends of the representation inward, we remove/count corresponding pairs of leading and trailing 1s until we can no longer do so. The total number of 1s (bits) removed is the original number's digital hardness value. For example, suppose that we have an integer whose binary representation is 110101010101 (the binary representation always begins with a leading 1). We remove the leading...

Is there such a thing as a “digital hoarder?” According to a recent news report, 52% of adults never delete any apps or files from any of their digital devices. Imagine that we choose a simple random sample of 145 adults and we ask these adults if they have ever deleted apps or files from any of their digital devices. We know the percentage of adults who answer “no” to this question will vary, or be different, from sample to...

A seven segment decoder is a digital circuit that
displays an input value 0 through 9 as a digital output in the
7-segment display. The behavior of this design can be modeled with
the schematic diagram below, where DCBA is the 4-bit input (D is
the most significant bit and A is the least significant bit) and
abcdefg is the 7-segment output.
