You're given a set of hotel rooms, each room has it's own priority and each room has a client.
You have to minimize the number of repeating clients in the hotel rooms, according to the rules:
Limitations:
0 < Rooms < 1000
0 < Priority < 10^9
'A' < Client < 'Z'
Input:
Output:
The following example shows:
- in the picture1 — client "B" is repeating.
- in the picture2 — there are no repeating clients.
Often I notice in CF posts apology sentences about bad English. I think this time has come!

Hi there!
I'm searching for good algorithms for the "Recommendation system". If you have any suggestions about what could be good, please let me know.
Confused...
Back-end part:
int[][] matrix = new int[n][m];
int[] array = new int[n*m];
traversMatrix(matrix);
traversArray(array);
Client part:
function traversMatrix(matrix : int[][])
for (i..n)
for (j..m)
doActions();
function traversArray(array : int[])
for (i..array.size())
doActions();
===================================
Time Complexity for traversMatrix: Quadratic
Time Complexity for traversArray : Linear?
Why?
Hello, the community!
I and my friend decided to create a channel where we post real code from production and show people where algorithmic code used in real life.
Actually we'd be thrilled to see you here
