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:
输入:items = [["phone","blue","pixel"],["computer","silver","lenovo"],["phone","gold","iphone"]], ruleKey = "color", ruleValue = "silver" 输出:1 解释:只有一件物品匹配检索规则,这件物品是 ["computer","silver","lenovo"] 。
示例 2:
输入:items = [["phone","blue","pixel"],["computer","silver","phone"],["phone","gold","iphone"]], ruleKey = "type", ruleValue = "phone" 输出:2 解释:只有两件物品匹配检索规则,这两件物品分别是 ["phone","blue","pixel"] 和 ["phone","gold","iphone"] 。注意,["computer","silver","phone"] 未匹配检索规则。
提示:
1 <= items.length <= 104
1 <= typei.length, colori.length, namei.length, ruleValue.length <= 10
ruleKey
等于 "type"
、"color"
或 "name"
