Given a GVDie object and an integer that represents the total sum desired as parameters, complete method rollTotal() in LabProgram class that returns the number of rolls needed to achieve at least the total sum. Note: For testing purposes, the GVDie object is created in the main() method using a pseudo-random number generator with a fixed seed value. The program uses a seed value of 15 during development, but when submitted, a different seed value will be used for each test case. Ex: If the GVDie object is created with a seed value of 15 and the input of the program is: 20 the output is: Number of rolls to reach at least 20: 6

Given a GVDie object and an integer that represents the total sum desired as parameters, complete method rollTotal() in LabProgram class
that returns the number of rolls needed to achieve at least the total sum.
Note: For testing purposes, the GVDie object is created in the main() method using a pseudo-random number generator with a fixed seed
value. The program uses a seed value of 15 during development, but when submitted, a different seed value will be used for each test case.
Ex: If the GVDie object is created with a seed value of 15 and the input of the program is:
20
the output is:
Number of rolls to reach at least 20: 6
