# What on earth does Array.Sort() do?

On the C# lesson where we learn about static classes, it has an array ( int arr[] = {9, 4, 10, 42}; ), and it asked what the first element would be if you used Array.Sort(). Why is the answer 3?

ANNA TOWNSEND Array.Sort() is use to sort the array elements is ascending order .
Sort() contains 1 parameter so we can sort array like this
Array.Sort(arr);
//after using this, array will be {4, 9, 10, 42)
first element will be 4 Because It's smallest value of array.

Answer is 3 because we are taking the square root of 2nd element using sqrt() method after sorting which is at 1 index.
