a) begin with C and end with R?
b) begin with R and end with C?
Answer by Edwin McCravy(20056)   (Show Source): You can put this solution on YOUR website!
The answers to both (a) and (b) are the same, as they are each
just the distinct permutations of "OMPUTE", which is 6! = 720.

That's because for each of the 720 distinct permutations of 
"OMPUTE" you can put a C on the far left and an R on the far 
right, or vice-versa.
