难度:⭐
题目描述:
给你一个数组 items
,其中 items[i] = [typei, colori, namei]
,描述第 i
件物品的类型、颜色以及名称。
另给你一条由两个字符串 ruleKey
和 ruleValue
表示的检索规则。
如果第 i
件物品能满足下述条件之一,则认为该物品与给定的检索规则 匹配 :
ruleKey == "type"
且ruleValue == typei
。ruleKey == "color"
且ruleValue == colori
。ruleKey == "name"
且ruleValue == namei
。
统计并返回 匹配检索规则的物品数量 。
示例1:
1 | 输入:items = [["phone","blue","pixel"],["computer","silver","lenovo"],["phone","gold","iphone"]], ruleKey = "color", ruleValue = "silver" |
示例2:
1 | 输入:items = [["phone","blue","pixel"],["computer","silver","phone"],["phone","gold","iphone"]], ruleKey = "type", ruleValue = "phone" |
提示:
1 <= items.length <=
1041 <= typei.length, colori.length, namei.length, ruleValue.length <= 10
ruleKey
等于"type"
、"color"
或"name"
所有字符串仅由小写字母组成
解题过程:
思路:遍历数组items,统计检索结果。
