Translate the following four bl programs into their executable form in the tables next to each example using the code generation "patterns" discussed in class (especially slides 30-47). use only the primitives: move, turnleft, turnright, infect, skip, and halt; unconditional jump: jump; and the conditional jumps: jump_if_not_next_is_empty, jump_if_not_next_is_not_empty, etc.) note that the tables may be bigger than the actual length of the generated code. program example4 is instruction turnbackandinfect is turnright turnright if next-is-enemy then infect end if end turnbackandinfectbegin while true do turnbackandinfect end whileend example4
