@DewanjeeS - Since @jeevith already provided a very good regex…I just sharing my views here…
Since Single Coded(2 words), Numeric is (1 word) I think capturing is little difficult(I may be wrong here) , so I have added or condition… feel free to add any options which comes …
Group1= Question#
Group2= Single or Numeric
I guess, in the previous post I have already provided how to capture between Not Back and Normal right?
