how do one prove that the language is inherently ambigous? like for example in languages that use unions such as
L = L1 U L2, where
L1 = {a^m b^m c^n | m,n>0}
L2 = {a^m b^n c^n | m,n>0}

is it fine?
the ques was actually this

what kind of help do you want? is it that you dont know HOW to solve your problem by use case diagram modeling or is it that the software you are using to draw is producing errors or whether you are having a hard time drawing use case diagram with that particular software?Leave a comment:

did i solve correct?
What will be the output of the following expression:
((a >> b) ^ c)& d
Where a = 12, b =2, c = 5 and d = 2
Ans ===> 010 (binary form) 2 (decimal form) -
I was not trying to be rude :( I was stating the problem...... i will check with the teacher straight away ..... i myself am confused ..... :(Leave a comment:
