The answer before the first query is $$$5$$$ because you can move all piles from $$$1$$$ to $$$2$$$ with one move, all piles from $$$10$$$ to $$$8$$$ with $$$2$$$ moves and all piles from $$$6$$$ to $$$8$$$ with $$$2$$$ moves. Codeforces Problemset Solutions All of the problems are under copyright of Codeforces.com. The real answer for the first example is $$$\frac{1}{4}$$$: with probability $$$\frac{1}{4}$$$, the towers are built in both towns $$$1$$$ and $$$2$$$, so we can set their signal powers to $$$1$$$.

After the fourth query, the set becomes $$$[1, 2, 4, 8, 9]$$$ and the answer is almost the same (the previous sequence of moves can be applied without moving piles from $$$10$$$). - bound1ess/codeforces-problemset Frequency Problem (Easy Version) data structures, greedy. Consist of all the problem solving of Codeforces. After the second query, the set of piles becomes $$$[1, 2, 4, 6, 8, 9, 10]$$$ and the answer is the same (and the previous sequence of moves can be applied to the current set of piles). 3) - 2/6 1454A - Special Permutation - Accepted; 1454B - Unique Bid Auction - Accepted; 1454C - Sequence Transformation - Accepted; 1454D - Number into Sequence - Accepted; Codeforces Round #685 (Div.
