Slove the following problems with ARM Assembly Instructions:

1. Instructions: Starting with MOV R1, #1 and now using ONLY multiple LSL R1, R1, #1 which effectively multiple R1 by 2 in each step, do this several time until you get the value 256 in R1

2. Instructions: Starting with MOV R1, #256 and now using ONLY multiple LSR R1, R1, #1 which effectively divides R1 by 2 in each step, do this several time until you get the value 1 in R1
