One effective method often used by programmers to comprehend the effect of cod is "tracing". Tracing is hand-exocuting the code in the same sequence and manner that the computer would execute the program. Often, the changes made to variables in the codk are recorded in a trace table". Each ow in the trace table records the values of the variables after a corresponding statement in the left hand column of the trace table has been hand-executed. For example, for the code ho1den2 ford 13 mitsubishi5 a completed trace table would be: holden ford mitsubishi holden -2 ford 13 mitsubishi5 13 13 Your task is to trace execution of the following Python code and keep track of variables Last and which: numbers1-,50, 500) numbera2-[10,20, 500 last-1 hich 0 While which if numbersi (which) >numbers2[which): last which which which 1
