Is this correct ?
I need to Prove that (w R)R = w for all w є∑*
Where w is a string and wR is reverse of w.
It looks pretty obvious and this is how I proved it. I was wondering
if it is correct!
Let w = abbbcaa
then wR, by defination, = aacbbba
Now if we again reverse the string wR then we will get abbbcaa = w.
Hence proved :D
Is that ok?
