Problem: Count Items Matching a Rule
Understand how to implement a linear search to count items matching a given rule within an array of item attributes in Java. This lesson helps you practice mapping keys to indices and efficiently iterating over data sets to find matches, building foundational searching skills.
We'll cover the following...
Statement
You are given an array items, where each items[i] = [type_i, color_i, name_i] represents the type, color, and name of the ruleKey and ruleValue, that together define a matching rule.
An item is considered a match if any of the following conditions holds:
ruleKey == "type"andruleValue == type_iruleKey == "color"andruleValue == color_iruleKey == "name"andruleValue == name_i
Return the total number of items in items that match the given rule.
Constraints:
