给定一个字符串和一个字符串列表，用相应的字符串填充输入字符串中的所有空格。
输入输出
输入字符串仅包含字母字符，空格和下划线。它是非空的，并且不以下划线开头。换句话说，输入字符串与正则表达式匹配^[a-z A-Z]([a-z A-Z_]*[a-z A-Z])?$
输入列表中的每个字符串都是非空的，并且仅包含字母数字字符和空格。换句话说，它们匹配正则表达式^[a-z A-Z]+$。
空白是下划线（_）的连续序列，下划线（）之前或之后都没有。
输入字符串包含n一些正整数的空格n，字符串列表恰好包含n字符串。
通过将k输入字符串中的每个-th空格替换为输入字符串k列表中的-th字符串来获得输出。
例
给定一个输入字符串"I like _____ because _______ _____ing"和一个字符串列表["ice cream", "it is", "satisfy"]，我们可以找到如下输出：
- 第一个空格紧随其后
"like "。我们"ice cream"用来填充它"I like ice cream because ______ _____ing"。 - 第二个空格紧随其后
"because "。我们"it is"用来填充它"I like ice cream because it is _____ing"。 - 第三个空格紧随其后
"is "。我们"satisfy"用来填充它"I like ice cream because it is satisfying"。
我们输出最后一个字符串"I like ice cream because it is satisfying"。
