The former (now dead) President had told him not to sell it unless he sees the president again“. He didn’t say “never sell it unless you meet the president again”. Ronald might have seen the President ‘n’ number of times (later) before his death.

Reading it in a different way:

The former President X had told him not to “sell it unless he sees the president again“. He didn’t say “never sell it unless you see ‘me’ again”. So, even though Ronald couldn’t meet President X again before his death, he could have sold it once he got an opportunity to meet (any) President Y who assumed Office subsequently, before selling it.

Either way, Mr. Ronald had sold it without breaking his promise.

Answer – It is daytime

One pigeon is  left dead (assuming that the shot hit the target);  Four pigeons left the fence (assuming that none of them is deaf or injured so that it can’t fly), and no pigeon is left on the fence as before…!  🙂

Same as what  means…

How about

Let the original order from viewer’s perspective be XZWY where W, X, Y and Z are the cards 3, 4, 5 and 6, NOT necessarily in that order. (Viewer’s perspective is considered because all movements are given in that perspective.)

Move 1: Left-most card moved to end => Result: ZWYX.
Move 2: Third from right (W) to the end => Result: ZYXW.

Since the final arrangement is ascending left to right from magician’s perspective, this must be descending order in viewer’s perspective. Replacing the letters with numbers as per the resulting arrangement, we get ZYXW is equivalent to 6543.  Hence, the original arrangement in viewer’s perspective XZWY = 4635, which, in turn, means that the original order from the magician’s perspective was 5364.
