Consider the following list: 2,10,17,45,49,55,68,85,92,98,110 Suppose that we are using binary search (as described in the class) and searching for the number 90 . What will be the values of the first and last variables after the second iteration of the while loop? Your answer: first=6last=8 first =6 last=10 first =0 last=4 first =6 last =7 first =5 last=7
