树状dp算法
This line of code initializes a dynamic programming array called "dp" with zeros. The "memset" function is used to set a block of memory to a particular value. In this case, it sets the block of memory associated with the "dp" array to zero. The "sizeof" operator is used to determine the size of the "dp" array in bytes, which is passed as the third parameter to the "memset" function.
