WebJan 31, 2024 · CDQ D&C is a offline technique invented by a China competitive programmer (called CDQ, obviously). CDQ D&C is almost same to normal D&C. The biggest difference between them is that suppose we cut a interval [ l, r) into [ l, m), [ m, r). In normal D&C, the elements from [ l, m) won’t influence [ m, r); In CDQ D&C, elemenst from [ l, m) will ...

The time complexity of a direct implementation of this formula (using dynamic programming) would be O ( N 2 C). We need to note that f (n,c) = f (n,c−1) + f (n−1,c) − f (n−1,c−n), which leads to a O (NC) solution. It is also possible to cut down on the memory used by keeping only two rows of the ...
