Solution

My Solution

func countPrefixSuffixPairs(words []string) int {
    count := 0
    
    for i, word := range words {
        for j:=i+1; j<len(words); j++ {
            if len(word) <= len(words[j]) && isPrefixAndSuffix(words[j], word) {
                count++
            }
        }
    }

    return count
}

func isPrefixAndSuffix(word1, word2 string) bool {
    return strings.HasPrefix(word1, word2) && strings.HasSuffix(word1, word2)
}
