The order in which the answer output is not considered.Solution:Class Solution {public:vector　　"Intermediate algorithm" 49. Alphabetical Groupi

search algorithm succeeds every time. For the lookup algorithm, the probability of finding success and finding failure is the same. Therefore, the average lookup length of the lookup algorithm should be the average lookup length when the lookup succeeds plus the average lookup length when the lookup fails.For a table with n data, each lookup fails, and the number of comparisons is n+1. So the average lookup length of the search algorithm is calculated as:This section mainly introduces the imple
