Kotlin Leetcode - 1662. Check If Two String Arrays are Equivalent

題目連接

class Solution {
    fun arrayStringsAreEqual(word1: Array<String>, word2: Array<String>): Boolean {
    
    }
}

解題思路

這一題考的是對字串陣列的處理

透過 reduce 將陣列歸約成一個單一字串

或者使用 joinToString

可以很快的解決這個問題

Kotlin 參考解答

class Solution {
    fun arrayStringsAreEqual(word1: Array<String>, word2: Array<String>): Boolean =
    word1.reduce {acc, e -> acc + e} == word2.reduce {acc, e -> acc + e}
}

使用 joinToString

class Solution {
    fun arrayStringsAreEqual(word1: Array<String>, word2: Array<String>): Boolean =
    word1.joinToString("") == word2.joinToString("")
}
