For the question : FRMQ Problem - CodeChef , I used the sparse table agorithm given here :Range minimum query - PEGWiki to create a chache and then process the queries. Im getting only 70 points and subtask 3 shows TLE. My code : CodeChef: Practical coding for everyone. Can anyone give me any suggestions?
Loose the % operation.
i tried that but still getting TLE on last dataset. my code CodeChef: Practical coding for everyone
You can precalc the
next_x[i] = (i + 7) % n next_y[i] = (i + 11) % (n - 1)
for each i in 0…n-1
then just make x = next_x[x], y = next_y[y].
I optimised the solution and was able to make it till here : CodeChef: Practical coding for everyone .I am not able to go more further than this. Can somebody help?
