Problem: Count Items Matching a Rule
Understand how to use linear search to count the number of items matching a specific rule based on type color or name. This lesson helps you implement a straightforward and efficient scanning algorithm in Java that accesses attributes by index for quick comparisons.
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.
