Smart card operating System COS overview

register, it is usually a 8-bit (or 16-bit) long area in memory ram as the discriminator register. The identification here refers to the identification of the security control password. The authentication register reflects the security status of the smart card in its current location. In this way, the file header (or file descriptor) of each file of a smart card usually stores the condition that the file can be accessed, generally including reading and writing two conditions, respectively, with

Knapsack Problem priority queue branch and restriction algorithm

This is probably an exercise question in the algorithm class. The so-called backpack problem can be described as follows: a thief steals a safe deposit box and finds there are n kinds of items of different sizes and values in the cabinet, but a thief only has a backpack with a volume of m to carry things. The problem with a backpack is to find out a combination of stolen things, so as to maximize the total value of stolen items. There are many ways to solve this problem. This program uses the br
