The University of Northern Florida has hired you to write an algorithm to schedule their final exams. Each semester, the university offers n different classes. There are r different rooms on campus and k different time slots in which exams can be offered. You are given two arrays E[1 .. n] and C[1 .. r], where E[i] is the number of students enrolled in the ith class, and C[j] is the number of seats in the jth room. At most one final exam can be held in each room during each time slot. Class i can hold its final exam in room j only if E[i] < C[j]. Describe and analyze an efficient algorithm to assign a room-time slot pair to each class (or report correctly that no such assignment is possible).

well cos like a ds it doesn't really die out, unlike for example, fifa, they always come out with a new version, so lets say your fifa 18 is charging you to update the teams and stuff, so, if messi were to go to real madrid (never gonna happen) it would switch messi to the other team, until the owners of fifa come out with fifa 19, then the game would eventually stop updating, and back to the ds, it doesn't really stop working after sometime because there's lots of things that it could be used for, and idk if u know what i'm saying, but long story short, samsung, represents the ds, if they still work, and people love them but not the new version, the old version still works, so they don't really force people to buy new phones, get me?

you can not change you age soon as you signed up. the only way is too delete your account and use another account to sign up and put your correct age.
