There are few things to consider while reading a problem.

  1. Understanding what is required to be calculated.
  2. Focus on the constraints.
  3. Focus on the time limit.
  4. Select appropriate algorithm to solve it successfully within the specified time limit.

Generally for n=1e6- O(nlogn), O(n) is required and for n<=5e3 O(n^2) is okay. Finally after deciding all these things. Start writing your code fast and bug free.
