We execute the following sequence of instructions in a stack using the stack architecture described in Lecture 11 Slides 7 and 8: PUSHA PUSH B ADD POP B PUSHA PUSH B ADD POP X Assume that, initially, Memory at address A contains 001010, B contains 000011, X contains 000000. At the end of executing the sequence of instructions, what are the contents of the memory? Memory at address B: Memory at address X:
