I have tried to use the Sparse Table Algorithm in order to compute the RMQ in this problem. However, this ends up timing out. I thought it was O(nlogn)?

Try mend your binary search, like here and your RMQ dubious

int k = floor(log(j-i+1));

Shouldn't it be log2(j — i + 1)? It would be better if you precalculate logarithms.
