For the following problems, consider the following piece of three-address code: 1. READ (A) 2. READ (B) 3. C=A+B 4" A=A+B 7. T2 = T1 + C 8. F=A+B 10. G T2 + B 11. T3 = F + B 12. WRITE (T3) 1. Perform liveness analysis on this piece of code, assuming that it is the entire code of the program. Show which variables are live after each of the statements in the program
