Expert Solution

Step 1: Introduction

Welcome to the fascinating world of assembly language, where every instruction is a testament to the raw power and flexibility of low-level programming. In today's exercise, we will decode sequences of assembly instructions and deduce the resultant value in the %rax register after each sequence is executed. Assembly language offers a granular perspective on how computers work and is often considered an art. With keen observation and careful interpretation, we will navigate through these sequences.
