Random now give A number A, how do I know that A is determined by A number of x addition results? (once each x only addition)
Such as the given number is 3, then know that are the result of x1 and x2 addition,

CodePudding user response:

X is not 2 base a weight? A corresponding 1 0, 1 corresponding 2, 3 corresponding 4, 4 corresponding to 8,,,,,,, random Numbers to watch the bit is 1, there is changed to the corresponding X

CodePudding user response:

Binary, which position is 1, corresponds to a few X

CodePudding user response:

5 turn binary for 0101, for example, will know have x1 x3
