A program trace is a listing of the contents of certain registers and memory locations at different times during the execution of a program. List the contents of registers RO, R1, and R2 after each of the first three executions of the BGT instruction in the program in Figure 3.7. Present the results in a table that has the three registers as column headers. Use three rows to list the contents of the registers after each execution of the BGT instruction. The program data are as given in Figure 3.8.
