有效地，您面临两种选择:

1.使用字符串索引找到第一个(的位置，然后使用它找到紧随其后的)(使用第一个(的索引(作为搜索的起始位置).索引，您将使用子字符串检索直到(的部分，然后从)到末尾.重复此过程，直到没有更多的( )序列.
2.使用正则表达式搜索(...)部分，然后将其替换为空字符串.

在编写和测试正则表达式时，我使用 Expresso [

Effectively you face two choices:

1. Use string indexes to find the position of the first ( and then use that to find the ) that follows it (use the index of the first ( as the starting position for your search). Now that you have the indexes, you would use substring to retrieve the part up to the (, and then from the ) to the end. Repeat this process until you have no more ( ) sequences.

2. Use a regular expression to search for the (...) parts, and replace them with an empty string.
