Removing elements

Theory Click to read/hide

You can remove elements in an ArrayList using the remove method in two ways:

  • by index remove(index)
  • by value remove(value)
For example:
  
arr.remove(0); //removes the first element
arr.remove(< strong>new Integer(10)); //deletes element with value 10

Problem

Input:
- the input is given in the first line N - the number of array elements;
- the second line contains N numbers - the values ​​of the array elements.

Output: print the resulting array to a string.
