How far is this list from sorted? Input: list of whitespace-separated base-10 integers (on stdin). Output: minimal count (base-10 integer) of numbers which have to be moved to a different position in order to sort the array (to stdout). Example List 0 1 2 4 5 6 3 9 7 8 becomes sorted by...

Input: a sequence of uppercase letters (ASCII [65;90]) which is the Nth* lexicographical permutation of the multiset of its characters *permutations are numbered from 0 upwards Output: base-10 integer N Rulez There might be duplicates (that's how this challenge differs from this one) The c...

Please how do you sketch the phase diagram and classify all equilibrium points of the system below?: x prime = -6y+2xy-8 y prime = y^2-x^2 I have found the critical points by setting each of x prime and y prime to be zero. Please what do I do next?

Your challenge is simple: write a program or function which appears to print the first ten numbers of any integer sequence (on OEIS, the answerer may choose which sequence), but instead prints the exact text: Happy April Fool's Day! if and only if it is run on April 1st of any year. Run on any...

Factor Sort This challenge involves sorting positive integers based on a lexicographical ordering of their prime factorizations. Overview lexicographical sorting, used in dictionaries, applies lexicographical order which extends alphabetical order to words: a aa aaa aaron ab abandoned abc abe...

I was working on a dataset of 21 columns and 9800020 rows in Rstudio.While I am doing regression for each item in my dataset separately for few Items I got regression score close to zero which is good enough but few items it is deviating more than 40 I used various regression algorithms like SVM,...

Input A stream of Integers is the search space. At any point of time, you will be given an Input N (also integer). Output Count of integers that are smaller than N, at that point of time. Example at time t1: stream : 1, 4, 3, 2, 6, 7 input : 5 output : 4 at time t2:...
