Question 4: [3 points) Write an ARM assembly code, which calculates the summation of the integer numbers from 1 to N, where N is an integer greater than 1. Assume that the value of N is stored in register ro. Sum= N Thus, the Sum will be equal to 1+2+3+.... + (N-1)+N The final result, named Sun, should be stored in register ri. Make sure that the original value of ro should not change
