QUESTION 1:
Create a function called findThrees that receives as a parameter a vector/array/list of numbers and returns the sum of all numbers in that vector/array/list that are evenly divisible by 3.
So if the vector/array/list was: {0,4,2,6,9,8,3,12}, the function would return 30 since (0+6+9+3+12) is 30.
QUESTION 2:
Create a function called dotProduct that receives two vectors/arrays/lists of numbers (say v1 and v2). The function returns what is the dot product of the two vectors/arrays/lists.
Example. If the input is {2,4,5,6} and {1,2,3,4} the result will be 49 since (2*1)+(4*2)+(5*3)+(6*4) is 49
