1. Write a sequence of instructions that would implement the following IF-THEN-ELSE structure. IF (9000H) is even THEN (9001H) 22H ELSE (9001H) 99H 2. You are given an array of 50 signed integers tored in 9000H write a program number of integers that are positive and save the count in 8900H. that would count the 3. You are given an array of signed integers stored in 21H. The end of the array is followed by a dummy end of data, oFFH. Write a program that would compute the checksum of only elements that are positive and odd and save the sum in 20H
