Bandwidth, transmission speed, two bytes, killing people, always confused which is bit, which is byte, the network speed is 10 m, M indicates bit or byte Article Article Record that Mbps is actually a bandwidth unit, not a speed unit. In Mbps, "B"

Question: It is known that a function rand7 () can generate a random number ranging from 1 to 7. Please provide a function that can generate a random number ranging from 1 to 10. Ideas: If we know that a function can generate a random number

Idea: If we were to fill 0 in front of the number , we would find that the N-bit all 10 binary number is actually N from 0 to 9 of the full array. That is to say, we arrange each digit of the number from 0 to 9, and we get all the 10 binary numbers.
