The document contains 3 code snippets that demonstrate recursion, array input and output, and array reversal. The first snippet uses recursion to output the series 2 4 6 8 10. The second takes 9 user inputs into an array, calculates the sum and product, and outputs both. The third takes input into an array of any size, then outputs the array in reverse order.
