There's a total of 2 different states of transition.When we move the state from X to Y, we can choose to change players or not to change players, but one thing to be aware of is that if you want to change players, it's just the latest game.And there's always an increase in the number of matches. We always from (x-1)---->x It is also logical that we must first play in the X-1 field in order to play in the X game.Dp[x,y] indicates that at the time of the current X game, I was numbering in Y for Dp

1. In order to implement the binary search algorithm, the N-bit register is first set to the intermediate scale (that is, 100... 00, and MSB is set to 1 ). In this way, the DAC output (vdac) is set to vref/2, and vref is the reference voltage provided to the ADC. Then, compare and determine whether vin is smaller than or greater than vdac. If Vin is greater than vdac, the MSB of the comparator output logic is 1 or 1, and the N-bit register is 1. Conversely, if vin is smaller than vdac, the compa
