What Does “Think Outside of the Box” Mean ?

 

 In the IT Industry one of the most well-worn phrase is a "Thinking Outside of the Box". It's all about creativity and doing the things in Best+ way. Think a situation like below

Calculate how many times one answer choice selected.

                    Choice 3 - 6 Times Selected
                    Choice 4 - 8 Times Selected
          

Think a best way to do this. You can use any no of Arrays and any other but avoid using if conditions and ternary operations. 

Answer -:  

public static void main(String[] args){
       
        int[] d = new int[]{4,2,3,3,4,4,6,2};
        int choises[] = new int[d.length];
        for(int i = 0; i<d.length; i++){
            choises[d[i]]++;
        }

        for(int val : choises){
                System.out.println(Integer.valueOf(val));
        }
}
