I have a variable Int a to set variable String b. if (a < 6){ b = “A”; } else if (a < 9){ b = “B”; } else if (a < 16){ b = “C”; }else{ b = “D”; } I want to optimize it like the following: array = [“A”, “B”, “C”, “D”];Read more

I’ve seen multiple things called legal in computer science (e.g. problems, solutions), and I’ve interpreted it as valid, meaningful or well-formed but what does it exactly mean and does it have a formal definition?Read more

Is the stable matching problem greedy or Dynamic ? Please anyone can give a strong explanation as i tried to find it on the net but it isn’t available.Read more

I have a list of data sets, each containing a list of key/value items. I now want to test if some of those KVs are related to each other. Related means that a KV1 always has the same value when KV2 has a specific value and KV1 changes only when KV2 changes. So they don’tRead more

In Complexity Theory and Cryptology: An Introduction to Cryptocomplexity By Jörg Rothe Proposition 6.35b gives $ $ coNP\subseteq SPP$ $ but has no proof. How to show this?Read more

I know that for standard page tables each process would have its own page table and for inverted the OS would have it. But other than this what are the main differences between a standard page table and an inverted one?Read more

The minimum number of comparisons required to determine if an integer appears more than $ n/2$ times in a sorted array of n integers is a:) Θ(n) b:) Θ(logn) c:) Θ(log∗n) d:) Θ(1) I need a little help in understanding this question. As per question “determine if an integer appears”. I am interpreting n itRead more

In description of select() system call Robert Love told “Well-designed code should never have to make use of FD_CLR” in chapter two of his book LINUX System Programming. But I can’t find the reason.Read more

I received an email from cPanel on 16986a.freshstores.co <cpanel@16986a.freshstores.co> stating that my Contact Information has been updated for: “fsi169834” and if I did not initiate this change, then contact my system administrator. It also said that I can disable the “ContactInfo::Change” type of notification through the cPanel interface: https://16986a.freshstores.co:2083/?goto_app=ContactInfo_Change I did NOT initiate any changes.Read more

Koning’s theorem states that the cardinality of the maximum matching in a bipartite graph is equal to the size of its minimum vertex cover. Wikipedia states that there is an equivalent version of the theorem for weighted graphs as well. I tried searching in a lot of places but could not find this theorem. ToRead more
