+/* Write a Java program that takes a user input integer n and prints the Fibonacci series up to n.
+
+The Fibonacci series is a series of numbers in which each number is the sum of the two preceding numbers. 
+The first two numbers in the series are 0 and 1. For example, the first 10 numbers in the Fibonacci series are: 
+0, 1, 1, 2, 3, 5, 8, 13, 21, 34.
+
+The program should use a for loop to generate the series.
+
+Sample Input:
+20
+
+Sample Output:
+0 1 1 2 3 5 8 13
+
+Explanation:
+The Fibonacci series up to 20 is: 0, 1, 1, 2, 3, 5, 8, 13. Therefore, the output is "0 1 1 2 3 5 8 13".
