This was a simple Kata. We have to find intersection of one array compared to another array. I initialized a variable "count" equal to 0. I looped through the given array and it can be any array as both the given arrays are of same length. Then I checked index of every element of first array in the second array and if the index returned was not equal to -1 then I incremented the count by 1.

In the end once the loop is finished I output the value of count as the solution to this Kata.
