Random Number problem-it is known that there is a Random7 () function, returns a random natural number from 1 to 7, so that the Random7 () is used to construct a random 1 ~ Random10 ~ 10. random7random10
Math. random () randomly generates the float number between (0, 1), an
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.
