I did this problem today. It mentions that person at the front will be served first. So, logically, we should remove him/her from further swap considerations. I got accepted assuming no effect on starting point with time. Have I done it improperly?.
I'm having trouble understanding the DP solution in 667C - Ребляндская лингвистика. Firstly, i am not able to comprehend that "How could I think in direction of reversing the string? (How could we know, that doing this would make it a DP problem?)". Also, i have tried implementing the method using pen paper, but still the intuition and approach towards the problem remains unknown to me. Thanks.
