03_ assembly language (n number to find maximum value)

Program Requirements:

　　First enter a number n (0<n<=100), and then enter n unsigned number K (0<=k<=65535) to find the maximum value of the n number and output

The test instance guarantees that after each number is entered, it will end with a carriage return
