解法一: 朴素模拟

go

func isAcronym(words []string, s string) bool {
    if len(words) != len(s) {
        return false
    }
    for i, word := range words {
        if word[0] != s[i] {
            return false
        }
    }
    return true
}

解法二: java 一行

java

class Solution {
    public boolean isAcronym(List<String> words, String s) {
        return Objects.equals(words.stream()
                .map(word -> String.valueOf(word.charAt(0)))
                .collect(Collectors.joining()), s);
    }
}
