1773. Count Items Matching a Rule Easy

1/**
2 * [1773] Count Items Matching a Rule
3 *
4 * You are given an array items, where each items[i] = [typei, colori, namei] describes the type, color, and name of the i^th item. You are also given a rule represented by two strings, ruleKey and ruleValue.
5 * The i^th item is said to match the rule if one of the following is true:
6 * 
7 * 	ruleKey == "type" and ruleValue == typei.
8 * 	ruleKey == "color" and ruleValue == colori.
9 * 	ruleKey == "name" and ruleValue == namei.
10 * 
11 * Return the number of items that match the given rule.
12 *  
13 * Example 1:
14 * 
15 * Input: items = [["phone","blue","pixel"],["computer","silver","lenovo"],["phone","gold","iphone"]], ruleKey = "color", ruleValue = "silver"
16 * Output: 1
17 * Explanation: There is only one item matching the given rule, which is ["computer","silver","lenovo"].
18 * 
19 * Example 2:
20 * 
21 * Input: items = [["phone","blue","pixel"],["computer","silver","phone"],["phone","gold","iphone"]], ruleKey = "type", ruleValue = "phone"
22 * Output: 2
23 * Explanation: There are only two items matching the given rule, which are ["phone","blue","pixel"] and ["phone","gold","iphone"]. Note that the item ["computer","silver","phone"] does not match.
24 *  
25 * Constraints:
26 * 
27 * 	1 <= items.length <= 10^4
28 * 	1 <= typei.length, colori.length, namei.length, ruleValue.length <= 10
29 * 	ruleKey is equal to either "type", "color", or "name".
30 * 	All strings consist only of lowercase letters.
