( The intuition is as follows: Hence, to detect negative cycles using the FloydWarshall algorithm, one can inspect the diagonal of the path matrix, and the presence of a negative number indicates that the graph contains at least one negative cycle. Commenting here as it's led me to overall the best answer here, it just has a mistake. for all Nevertheless, if there are negative cycles, the FloydWarshall algorithm can be used to detect them. No matter, you can reverse the ordering of your data simply by negating it: %note that it's 3.9 instead of 4 due to the way histcounts treat the last bin, count is the reversed cumulative histogram starting at 4, finishing at 5.9. t e Therefore, the complexity of the algorithm is k Asking for help, clarification, or responding to other answers. a {\displaystyle \{1,2,\ldots ,N\}} | s {\displaystyle k=0} I have an array of values, some of which have duplicates, for example: and I would like to find which are duplicates, and then number each of these sequentially, while making non-duplicates zero. functions for a better understanding of how the above code works.
