Given an array of ints, return the number of times that one element is directly followed by another element with a value of one greater. Thus, if the element at index 3 has the value 40 and the element at index 4 has the value 41, that counts once toward the number you are building.

You will need to compare two side-by-side elements using your loop control variable and either the variable plus one or minus one. Be careful about the edge cases at the beginning and end!
