Thoughts

• Maybe it's better to splice range equally into min and max.
• Like [-2000, 3001] cut to 4 pieces. The initial pieces is min 1 and max 2 with 2000 steps, So it's better to set min and max equal and find no remaining count then return.
• More commonly if the min has X and max has Y pieces, but we remain k pieces. We should first try to set X and Y equally, then we separate remaining tictcount into the two parts seems better.
