/*2.对称字符串
 传入一个字符串,将这个字符串组合成一个新的对称字符串返回
 例如:
 传入:@"I love you Mery"
 返回:@"I love you Mery Mery you love I"
 */

//2, 字符串分割 @“I #am Prime  # # #Optimus”
//字符串分割函数  按照 @" #"字符串整体分割


//3有两个字符串@"I am a good girl hello world";@"You are a bad boy"; 将这两个字符串单词,交叠,形成新的字符串 @"I You am are a a good bad girl boy"
