A sentence S is given, composed of words separated by spaces. Each word consists of lowercase and uppercase letters only.git
We would like to convert the sentence to "Goat Latin" (a made-up language similar to Pig Latin.)github
The rules of Goat Latin are as follows:微信
"ma" to the end of the word."ma"."goat" becomes "oatgma".'a' to the end of each word per its word index in the sentence, starting with 1."a"added to the end, the second word gets "aa" added to the end and so on.Return the final sentence representing the conversion from S to Goat Latin. app
Example 1:ui
Input: "I speak Goat Latin" Output: "Imaa peaksmaaa oatGmaaaa atinLmaaaaa"
Example 2:spa
Input: "The quick brown fox jumped over the lazy dog" Output: "heTmaa uickqmaaa rownbmaaaa oxfmaaaaa umpedjmaaaaaa overmaaaaaaa hetmaaaaaaaa azylmaaaaaaaaa ogdmaaaaaaaaaa"
Notes:code
S contains only uppercase, lowercase and spaces. Exactly one space between each word.1 <= S.length <= 150.给定一个由空格分割单词的句子 S。每一个单词只包含大写或小写字母。component
咱们要将句子转换为 “Goat Latin”（一种相似于 猪拉丁文 - Pig Latin 的虚构语言）。htm
山羊拉丁文的规则以下：
"ma"。"apple"变为"applema"。
"ma"。"goat"变为"oatgma"。'a'，索引从1开始。例如，在第一个单词后添加"a"，在第二个单词后添加"aa"，以此类推。
返回将 S 转换为山羊拉丁文后的句子。
示例 1:
输入: "I speak Goat Latin" 输出: "Imaa peaksmaaa oatGmaaaa atinLmaaaaa"
示例 2:
输入: "The quick brown fox jumped over the lazy dog" 输出: "heTmaa uickqmaaa rownbmaaaa oxfmaaaaa umpedjmaaaaaa overmaaaaaaa hetmaaaaaaaa azylmaaaaaaaaa ogdmaaaaaaaaaa"
说明:
S 中仅包含大小写字母和空格。单词间有且仅有一个空格。1 <= S.length <= 150。1 import XCTest 2 class Solution { 3 func toGoatLatin(_ S: String) -> String { 4 let vowels = ["a", "e", "i", "o", "u"] 5 var result = "" 6 S.split(separator: " ").enumerated().forEach { i, word in 7 guard let firstChar = word.first.map(String.init) else { return } 8 if !vowels.contains(firstChar.lowercased()) { 9 result.append(word.dropFirst() + firstChar + "ma") 10 } else { 11 result.append(word + "ma") 12 } 13 result += String(repeating: "a", count: i + 1) + " " 14 } 15 return String(result.dropLast()) 16 } 17 }
