[Template applet] adds a large number in decimal format (positive integer version + negative number version), including validity check and negative number of digits
To adapt to different purposes, the big number algorithm is written into two versions, namely, the version that only processes positive integers and the ve
Python Classic ExercisesThe answers that can be searched online are: for in range (1,85): If 168% i = = 0 := 168/ i ; if and and (i-j)% 2 = = 0 := (i + j)/ 2 = (i-j)/ 2 = n * n-100 pri NT(x)The output answers are:-99212611581But in fact, four figures are not in accordance with the conditions of +100 and +168, which are still the full square number;The correct code is as follows:Import= 0
Here are three ways I've learned, and if you have a better way to talk about it.
First, we need to know how the decimal system is converted into binary, as shown below.
Get a 10 binary number of 1010
Then we'll find out that 10%2 is the last one to determine whether a binary number is 0 or 1, when the judgment is complete, move to the right one that is 10/2 to 5, and then 5%2 to determine whether the p

The common method of finding prime numbers is to determine whether a number n is prime (only 1 and itself can divide itself) according to
