Mirko got a summer internship in a big IT company. This company builds a large database consisting of rows and columns.
On his first day, Mirko received a total of queries. Each query consists of numbers. However, some numbers got lost during transition, so they are denoted with -1
. Mirko wants to know how many rows of the database correspond to the query, i.e., how many rows of the database have identical numbers as the query, excluding -1
.
For example, if the query is in the form of -1 3 2
, then we need to count the rows of the database that have any number in the first column, have the number 3 in the second column, and have the number 2 in the third column.
