It will take 10 seconds for all of the comparisons.
A sequential search algorithm that starts at one end and goes through each element of a list until the desired element is found, otherwise the search continues till the end of the data set is called Linear Search.
Worst-case time complexity of linear search algorithm is O(N).
Since it takes at most 5 comparisons, there are 5 pairs (or 10 socks) in the drawer.
Time taken for each comparison is 1 second.
Therefore, time taken for all of the comparisons = 10 x 1 = 10 seconds.
Hence, time taken for all of the comaprisons is 10 seconds.
