 This is my first code to show here .

1. Fibonacci series ----

static void fibonacci(int n){
    int n1=0;
    int n2=1;
    int n3;
    for (int i=0; i<n; i++){
        System.out.println(n1);
        n3=n1+n2;
        n1=n2;
        n2=n3;
    }
}

fibonacci(n: 10);

output: 0 1 1 2 3 5 8 13 21 34
