Q12 
Which of the following is an appropriate explanation of the Boyer-Moore method? 
 
a) It is an aggregation algorithm that reads the records that are sorted with key items in 
order, categorize the records that have the same value of key items as a same group, 
and calculates the sum of the records. 
b) It is an n-th order solution algorithm that is used when an approximate solution is 
found, approximates a true solution by calculating a tangential equation in an 
approximate solution. 
c) It is a shortest path search algorithm that decides the minimum cost up to all nodes by 
finalizing the node that has the minimum cost among the nodes whose paths are 
clarified. 
d) It is a string pattern matching algorithm that decides the amount of movement of a 
partial string on the basis of whether the last character of the partial string that is 
extracted from the search target is present in the string to be searched for or not.
