Hello, I am trying to generate all permutations and for each permutation I am checking if the given conditions are satisfied and then counting it as part of the solution. But this approach times out as the time complexity is n*n!

I am not able to understand as to what can be precomputed.

Any help is appreciated.

Hello, I am using an interval tree to solve this problem but for 2 test-cases my solution are timing out. I have provided a drawing for the sample input given in the problem description.

0-8
                 /    \
                /      \
               /        \
             0-3         3-8
            /  \        /   \
           /    \      /     \
       0-2       2-3  3-6    6-8

Each time, I am adding a new interval I am returning the max diff of intervals to the root node and returning it as an answer

Could you please help me
