I cannot interpret this pseudocode. Can anybody explain to me how this program works and flows? Given this pseudocode that searches for a value in a linked list and a list that is in an ascending order, what would this program return?
a. The largest value in the list that is smaller than target
b. The largest value in the list that is smaller than or same as target
c. The smallest value in the list that is larger than or same as target
d. Target
e. The smallest value in the list that is larger than target
And say that List is [1, 2, 4, 5, 9, 20, 20, 24, 44, 69, 70, 71, 74, 77, 92] and target 15, how many comparisons are occurred? (here, comparison means comparing the value of target)
