Consider a relation r(abcdefghilu) with the following set of functional dependenciesg = {f → ab, cd → e, c → fg, h → ij, d → h }1. is cde a superkey of r (wrt g)? 2. is cde a key of r (w. rt g)? 3. apply the appropriate algorithm to determine a key for r (w. rt. g) 4. apply the appropriate algorithm to determine all the keys for r (w. rt. g). 5. determine the prime attributes of r 6. is r in bcnf (w. r.t. g)? 7. is r in 3nf (w. r.t. g)? 8. determine whether the decomposition d cde, cfg, dh, hij, fab has () the dependency preservation property and () the lossless join property, with respect to g. also determine which normal form each relation in the decomposition is in.

Write a program that takes in 3 inputs [players (int type), expected game time (double type), team (char type)] and calculates actual game time (double) based on the following conditions: if the number of players or the expected game time is less than or equal to zero, it should output wrong input if the number of players is greater than 0 and less than or equal to 6 and if they are on the â€r’ or â€r’ team, their game time will be 10% faster. and if they are on the â€b’ or â€b’ team, their game time will be 15% faster. and if they are on the â€y’ or â€y’ team, their game time will be 20% faster. and if they are on any other team, they will play 0% faster. if the number of players is greater than 6 but less than or equal to 12 and if they are on the â€r’ or â€r’ team, their game time will be 20% faster. and if they are on the â€b’ or â€b’ team, their game time will be 25% faster. and if they are on the â€y’ or â€y’ team their game time will be 30% faster. and if they are on any other team, they will play 0% faster. if the number of players is greater than 12 but less than or equal to 18 and if they are on the â€r’ or â€r’ team, their game time will be 30% faster. and if they are on the â€b’ or â€b’ team, their game time will be 35% faster. and if they are on the â€y’ or â€y’ team, their game time will
