Integer numStudents is read from input as the number of elements in the vector that follows. Then, numStudents elements are read from input into the vector runningNumbers. Use a loop to access each element in the vector and if the element is equal to 3, output the element followed by a newline.
Ex: If the input is
8 3 3 86 65 3 53 195 3
then the output is:
3 3 3 3
