+// Coding Challenge 1
+
+/*
+Julia and Kate are doing a study on dogs.So each of them asked 5 dog owners
+about their dog's age, and stored the data into an array (one array for each). For;
+now, they are just interested in knowing whether a dog is an adult or a puppy.
+A dog is an adult if it is at least 3 years old, and it's a puppy if it's less than 3 years;
+old.
+Your tasks:
+Create a function 'checkDogs', which accepts 2 arrays of dog's ages
+  ('dogsJulia' and 'dogsKate'), and does the following things:
+1. Julia found out that the owners of the first and the last two dogs actually have;
+cats, not dogs! So create a shallow copy of Julia's array, and remove the cat
+ages from that copied array(because it's a bad practice to mutate function
+parameters);
+2. Create an array with both Julia's (corrected) and Kate's data;
+3. For each remaining dog, log to the console whether it's an adult ("Dog number 1
+is an adult, and is 5 years old") or a puppy ("Dog number 2 is still a puppy
+🐶 ");
+4. Run the function for both test datasets
+Test data:
+§ Data 1: Julia's data [3, 5, 2, 12, 7], Kate's data[4, 1, 15, 8, 3]
+§ Data 2: Julia's data [9, 16, 6, 8, 3], Kate's data[10, 5, 6, 1, 4];
+Hints: Use tools from all lectures in this section so far 😉
+GOOD LUCK 😀
