Each year, the government releases a list of the 10000 most common baby names and their frequencies (the number of babies with that name). The only problem with this is that some names have multiple spellings. For example,"John" and ''Jon" are essentially the same name but would be listed separately in the list. Given two lists, one of names/frequencies and the other of pairs of equivalent names, write an algorithm to print a new list of the true frequency of each name. Note that if John and Jon are synonyms, and Jon and Johnny are synonyms, then John and Johnny are synonyms. (It is both transitive and symmetric.) In the final list, choose the name that are lexicographically smallest as the "real" name.
\r\n\r\nExample:
\r\n\r\n\r\nInput: names = ["John(15)","Jon(12)","Chris(13)","Kris(4)","Christopher(19)"], synonyms = ["(Jon,John)","(John,Johnny)","(Chris,Kris)","(Chris,Christopher)"]\r\nOutput: ["John(27)","Chris(36)"]\r\n\r\n
Note:
\r\n\r\nnames.length <= 100000
每年,政府都会公布一万个最常见的婴儿名字和它们出现的频率,也就是同名婴儿的数量。有些名字有多种拼法,例如,John 和 Jon 本质上是相同的名字,但被当成了两个名字公布出来。给定两个列表,一个是名字及对应的频率,另一个是本质相同的名字对。设计一个算法打印出每个真实名字的实际频率。注意,如果 John 和 Jon 是相同的,并且 Jon 和 Johnny 相同,则 John 与 Johnny 也相同,即它们有传递和对称性。
\n\n在结果列表中,选择 字典序最小 的名字作为真实名字。

示例:
\n\n\n输入:names = [\"John(15)\",\"Jon(12)\",\"Chris(13)\",\"Kris(4)\",\"Christopher(19)\"], synonyms = [\"(Jon,John)\",\"(John,Johnny)\",\"(Chris,Kris)\",\"(Chris,Christopher)\"]\n输出:[\"John(27)\",\"Chris(36)\"]\n\n
