Re: How to preprocess part of information of excel in CP

I understand your code now. Thank you very much for your explanation.

However, I face another problem.

 If I have a vector 

DisciplineForLargeroom =   [{“Biology”} {“Economy” “d”} {“French”} {“Geography”} { } {“History”} {“Maths”
         “g”} {“Physics”} {“Sport”} { } {“a”} {“e”} {“c”} {“b”} {“f”}]

 how can I separate “Economy” and “d” to become two distinct instance, and 

how  can I remove { } out of the set,

when I want the result as

DisciplineForLargeroom =   [{“Biology”} {“Economy”} { “d”} {“French”} {“Geography”}  {“History”} {“Maths”}
         {“g”} {“Physics”} {“Sport”} {“a”} {“e”} {“c”} {“b”} {“f”}]
