// Write the pseudocode for the algorithm on the left (Add  5+...+1).  Generally it compute the sum of a number from the upper bound (5) to the lower bound (1)

Declare and initialize counter  i
Declare and initialize sum

Loop
Load memory location i
Assign value in I to Data
Load memory location END
         If Data is 0 then Jump to location END; if not continue next  intr
Load memory location sum
Add data (current value of i) to sum (memory of sum)
         Load memory location i
Decrease I by 1
Load memory location LOOP
Jump to LOOP to execute next round

END
         Load memory location END
         Jump until halt
