Write the game of Nim in C ++)

The game of Nim is a well-known game with many versions. the following version has an interesting winning strategy. the two participants exchange several numbers from a pile of stones, and the number is determined by the participants themselves. however, each participant is required to retrieve at least one, at most half, and the other participant continues. participants who get the last Stone will lose the game.
Write a program that allows computers to compete with people. A random number is generated between 10 and 100 as the initial number of stones. then, 0 or 1 is randomly generated to determine whether the computer is playing first or the person is playing first. then, 0 or 1 is randomly generated to determine whether the computer adopts the "smart" or "stupid" mode. in the stupid mode, when it is the computer's turn, the computer simply removes the random number of stones (between 1 and N/2). In the smart mode, the computer removes a certain number of stones each time, so that the remaining number of stones is a power minus 1 of 2, such as 3, 7, 15, 31, 63. this is always feasible, unless the current number of stones is exactly a power minus 1 of 2. in this case, the computer removes the random number of objective stones.
You will find that when a computer is smart and comes first, it will never be defeated unless the number of original stones is accidentally a power minus 1 of 2. for example, 15,31, 63. of course, if a person is a pioneer and knows the winning strategy, the computer can also be defeated.
