【Python】is_prime number 对于一个素数的判定,一般来说是除了一和自身以外不可以被其他数整除。但是换一种方式想,这是两种情况,如果这个数本身就是1,那么不是素数,如果能被2或者以上的数字整除,意味着判断范围可以从2-自身减少到2-自身/2 如下: def is_prime(x):...

If the number does not belong to Tc (after using the 22 algorithms) then the number is prime. Each of these algorithms can be used independently on different computers or on a parallel computer. For example : 4921 is at the position (234,2) of the matrix 6x6 belonging to Tc. Its ...
