This question To[i][j] for the first person to send J this gift probability we use 13 to compress this left the number of gifts, so we will dp[i][k] expressed as the first person to put the gift after the state is K, then through the memory of the search we get the state probability that we want to Dp[i][k]+={dp[i+1][k-aj]*to[i][aj]}, well now if I go get the first gift I right probability, we can first know good friend put first probability forAssuming S is the state of the original giftPop=dp[

Analysis:Use 0, 1, 2, and 3 to indicate the clock status, indicating, respectively.Repeated results are generated after four operations, so 0 ~ 3,4 ^ 9 is also very limited,The status is small, and the impact of opera

ProblemIf the array name can be used as a constant pointer, will the pointer also be used as an array name?How arrays are accessed
Access the elements in the array in the following form
Accessing elements in an array as pointers
Subscript form vs Pointer form
The efficiency is higher than the subscript when the pointer moves in the array in fixed increments
Higher efficiency when the pointer increment is 1 and the hardware increments the model
