统计匹配检索规则的物品数量

1773. 统计匹配检索规则的物品数量 (Easy)

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 ruleKeyruleValue 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"ruleValue == typei
  • ruleKey == "color"ruleValue == colori
  • ruleKey == "name"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""name"
  • 所有字符串仅由小写字母组成
