OUTPUT 2014

The following functions are part of some class
i) What will be the output of fun1() when the value of s[] ={‘J’,’U’,’N’,’E’} AND X= 1?
ii) What will be the output of fun2() when the value of n =”SCROLL” ?
iii) State in one line what does the function fun1() do apart from recursion

void fun1(char s[], int x)
    {
        System.out.println(s);
        char temp;
        if(x<s.length/2)
        {
            temp=s[x];
            s[x] = s[s.length-x-1];
            s[s.length-x-1]=temp;
            fun1(s, x+1);
        }
    }
    void fun2(String n)
    {
        char c[]=new char[n.length()];
        for(int i=0;i<c.length; i++)
        c[i]=n.charAt(i);
        fun1(c,0);
    }
