Hi,
I think this method will work:
Possible Number of A's = N/2(1+R)
where R=N-(N/2+3)
assuming 11/2 = 5
Thanks

but my output : m =20: For first 5 times hit 'A', then ctrl+A, ctrl+C
resulting in 7 keystrokes. then 3 times ctrl+V, which result in m = 20.
Try this on a notepad. you will only 15A's

According to me Nishaanth's solution is incorrect, as let for n =10, your
output : m=16
but my output : m =20: For first 5 times hit 'A', then ctrl+A, ctrl+C
resulting in 7 keystrokes. then 3 times ctrl+V, which result in m = 20.

How about the following dynamic programming solution.
Let dp[i] be the max no of As with i keystrokes.
dp[i]=max(dp[i-1]+1,2*dp[i-3])
dp[N] is the required solution.
Correct me if i am wrong.

Given
1. A
2. Ctrl+A
3. Ctrl+C
4. Ctrl+V
If you can only press the keyboard for N times (with the above four
keys), please write a program to produce maximum numbers of A. If
possible, please also print out the sequence of keys.
So the input parameter is N (No. of keys that you can press), the
output is M (No. of As that you can produce).
Thanks Regards
Shashank Mani
