Write the programs in C# in Unity environment

To determine whether a year is a leap year, the algorithm is:

1. If the year is evenly divisible by 4, go to step 2. Otherwise, go to step 5.

2. If the year is evenly divisible by 100, go to step 3. Otherwise, go to step 4.

3. If the year is evenly divisible by 400, go to step 4. Otherwise, go to step 5.

4. The year is a leap year (it has 366 days).

5. The year is not a leap year (it has 365 days). For example, the years 2000 and 2020 are leap years, while the years 1800 and 1900 are not leap years. Write a function called LeapYear( ) which count how many leap years between (and including) the year 1700 and 2100
