Gosh... I've spent so much time on this problem... It shouldn't be difficult

anyone getting confused with the problem statement and misof's definition, plz just re-read this lines, you'll get everything at a glance!

... we find many of the editors and spreadsheet applications using colors or emphasized fonts to show the nesting of the parenthesis structure...

each bracket is turned into a letter! thats all!
this is good problem in sense of "understanding the problem statement"

Here is a good special case:

Result :Valid, Unique
