Integers seedVal, minVal and maxVal are read from input. minVal and maxVal represent the minimum and maximum numbers of keychains to be put in each basket, respectively. A total of $120$ keychains are available. Complete the following tasks:

Call randGen's setSeed$()$ with seedVal as the argument.

Assign variables basket$1,$ basket$2,$ and basket$3$ each with a random number of keychains between minVal and maxVal, both inclusive.

Assign variable remainingKeychains with $120$ minus the sum of basket$1,$ basket$2,$ and basket$3.$
