How to remove all characters between two brackets?
Such as "12345 (rtetnj) dsfd (fddsgd) dsf "----> "12345 dsfd dsf "
Use regexp syntaxes ,it's too simple .
Function StringWithoutBrackets(ByVal s As String) As String
With CreateObject("VBSCRIPT.REGEXP")
.Global = True
.Pattern = "[(][^)]*[)]"
StringWithoutBrackets = .Replace(s, "")
End With
End Function

Sub test()
MsgBox StringWithoutBrackets("12345 (rtetnj) dsfd (fddsgd) dsf ")
End Sub

C - Brackets Stack Query / Time Limit: 3 sec / Memory Limit: 1024 MiB Score : 300 points Problem Statement A string T is called a good bracket sequence if and only if it satisfies the following condition: T can be made into an empty string by repeating the following operation zero or more times: Choose () contained in T as a (contiguous) substring and remove it. For example, (), (()()), and the empty string are good bracket sequences, but )()( and ))) are not good bracket sequences. There is a string S. Initially, S is an empty string. Process Q queries in the order they are given. After each query, determine whether S is a good bracket sequence. There are two types of queries: 1 c: A character c is given. c is either ( or ). Append c to the end of S. 2: Remove the last character of S. It is guaranteed that S is not an empty string at this time. Constraints 1≤Q≤8×10 5 c in queries of the first type is ( or ). It is guaranteed that S is not empty when a query of the second type is given. Q is an integer. Input The input is given from Standard Input in the following format, where query i ​ denotes the i-th query. Q query 1 ​ query 2 ​ ⋮ query Q ​ Each query is given in one of the following two formats: 1 c 2 Output Output Q lines. The i-th line should contain Yes if the string S immediately after processing the i-th query is a good bracket sequence, and No otherwise. Sample Input 1 Copy 8 1 ( 2 1 ( 1 ) 2 1 ( 1 ) 1 ) Sample Output 1 Copy No Yes No Yes No No No Yes S immediately after processing the 1st query is (, which is not a good bracket sequence. S immediately after processing the 2nd query is an empty string, which is a good bracket sequence. S immediately after processing the 3rd query is (, which is not a good bracket sequence. S immediately after processing the 4th query is (), which is a good bracket sequence. S immediately after processing the 5th query is (, which is not a good bracket sequence. S immediately after processing the 6th query is ((, which is not a good bracket sequence. S immediately after processing the 7th query is ((), which is not a good bracket sequence. S immediately after processing the 8th query is (()), which is a good bracket sequence.c++
