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.
If we know that a function can generate a random number
Top K Algorithm DetailedApplication Scenarios:The search engine logs all the retrieved strings used by the user each time they are retrieved through a log file, with a length of 1-255 bytes for each query string.Assume that there are currently 10
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.
With Π/4≈1-1/3 + 1/5-1/7 + ... The formula asks for the approximate value of π until the absolute value of an item is found to be less than 10^6.
