* Create find_relative_maximum_point_count.js print number of relative maximum points in array runs in O(n) * rename file to match requested casing * add inline comments and greater documentation * fix wrong reference to algorithm explanation * remove live code and fix function misnaming * add multiple cases tests * add last line as empty line * git pull * style changes * move tests to test folder * chore: fix spelling * fix package-lock * revert to old lock file * chore: add line feed Co-authored-by: Rak Laptudirm <raklaptudirm@gmail.com>
