Thread: data structures question

so i have a interview on data structures. i am sure they will ask question on 1d arrays. but what can they ask me?

1.give a array find the max and min value.
2.give a array find avg.
3.sum of all value in array
4....

what else can they ask about 1d array?? or you can give me website which have question on arrays.

what exception will be thrown if you try to access an array like so:

int[] myArray = new int[3];
myArray[3] = 7;

When you create an int array, what are the initial values of all items?
What about arrays of other primitives such as double, float, char,...?
When you create a reference array (such as an array of String or Date, or any other reference non-primitive type), what initial values will it hold?

..sort, ascending and descending
..reverse an array
..shuffle an array
..see if an array contains a value
