Write an assembly program with a loop and indexed addressing thet exchanges every pair of values in an array with an even number of elements. Therefore, item i will exchange with item i+1, and item i+2 will change with item i+3, and so on.2. Use a loop with indirect or indexed addressing to reverse the elements of a byte array in place. Do not copy the elements to any other array. 3. Write an assembly program to add two 32-bit numbers (BX:AX and DX:CX) and store the result to BX:AX
