Python
One effective method often used by programmers to comprehend the effect of code is "tracing" Tracing is hand-executing the code in the same sequence and manner that the computer would execute the program Often, the changes made to variables in the code are recorded in a "trace table". Each row 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 holden a 2 ford 13 mitsubishi 5 a completed trace table would be: ford holden mitsubishi holden 2 13 ford 13 mitsubishi 5 Your task s to trace execution of the following Python code and keep track of variables index, where and answer numa (3r 1, 2, 10) where 0 for index in range (1, en (nums) if num lindex nums [where where index answer nums [where]Explanation / Answer
Answer: See the trace table below:
Trace table:
index where answer nums = [3,1,2,10] - - - where = 0 - 0 - for index in range(1,len(nums)): 1 0 - #<first iteration of the loop> if nums[index] < nums[where]: 1 0 - where = index 1 1 - #<second iteration of the loop> if nums[index] < nums[where]: 2 1 - where = index - - - #<third iteration of the loop> if nums[index] < nums[where]: 3 1 - where = index - - - #<end loop> answer = nums[where] 3 1 1Related Questions
