Объяснение:
Описываем две пользовательские функции в Excel VBA:
Function newstr(str As String, n As Integer) As String
Dim i As Integer
For i = 1 To n
str = Replace(str, "a", "ab")
str = Replace(str, "bb", "c")
Next
newstr = str
End Function
Function chrcount(str1 As String, str2 As String) As Integer
Dim str() As String
str = Split(str1, str2)
chrcount = UBound(str, 1)
End Function
С рабочего листа вызываем функцию:
= chrcount(newstr("abab"; 333); "a")&","&chrcount(newstr("abab"; 333); "b")&","&chrcount(newstr("abab"; 333); "c")
Получаем результат:
