Question

Suppose you have written a simple search program as follows: def findIt(ar, x): for i in range (len(ar)): if (x != int(ar[i])): return i return -1 v = [24, 20, 29, 32, 34, 29, 49, 46, 39, 23, 42, 24, 38] a = int(input("search for: ")) print (findIt(v, a)) For every number except 24, the output is 0. For 24 (which should have an output of 0) the output is 1. Which variable should be included in a debugging statement before the return to find the problem? (1 point) Responses i i ar ar ar[i] ar[i] x

Answer 1

To diagnose the issue with your findIt function, you should include a debugging statement that checks the value of ar[i] before the return statement. This is because the logic of your program relies on the comparison between x and ar[i], and observing the qualities of ar[i] during the iterations will help identify why the function misbehaves for the input value 24.

The line to include for debugging could look something like this:

print(f"Comparing x: {x} with ar[{i}]: {ar[i]}")

This will allow you to see what ar[i] is at each iteration of the loop and understand why the function is returning prematurely.
