Count Items Matching a Rule - LeetCode
You are given an array items
, where each items[i] = [typei, colori, namei]
describes the type, color, and name of the ith
item. You are also given a rule represented by two strings, ruleKey
and ruleValue
.
The ith
item is said to match the rule if one of the following is true:
ruleKey == "type"
and ruleValue == typei
.ruleKey == "color"
and ruleValue == colori
.ruleKey == "name"
and ruleValue == namei
.Return the number of items that match the given rule.
items = [["phone","blue","pixel"],
["computer","silver","lenovo"],
["phone","gold","iphone"]]
ruleKey = "color"
ruleValue = "silver"
if ruleKey == "type":
key = 0
elif ruleKey == "color":
key = 1
else:
key = 2
i = 0
while i < len(items):
if items[i][key] == ruleValue:
print(i)
break
i += 1
