/*
    Common Theory : 
    

    1. To find number of elements less than k in array a
       answer would be int res = upper_bound(all(a),k) - a.bg

    2. To find number of elements greater than k in array a
       answer would be int res = a.ed - upper_bound(all(a),k)

    3. Min Heap = priority_queue<int,vector<int>, greater<int>> que;
       Max Heap = priority_queue<int> que;

    4. Is Function Monotonus, Can you solve for a given res?
       Think about Binary Searching !

    5. Can't be sure if greedy is optimal? Constraints are low?
       Think about Dynamic Programming !

    6. Don't forget a grid is a graph.

    7. Watch out for function overhead

    8. Confused ? Think against these algos

       1. Prefix,Suffix
       2. Difference Array
       3. Nx32 Bit Frame
       4. DP ~ Can you create a state transition from dp[i][j] to dp[i-1][j] or dp[i][j+1]
       5. Sliding Window
       6. Hashing

    9. Guess from Solution's Expected Time Complexity

    10. Sometimes it's easy to solve the complement of a problem.

    11. If the constraints go up to 10^18, there can only be two solution
        1. Solve it in Log(n)
        2. Solution for bigger values is a constant
