[Solidity] How to remove an array element

Syntax

To remove an array element in Solidity, use the pop method.

Note that the element to be removed is the last element in the array.

array.pop();

pragma solidity >=0.7.0 <0.9.0;

contract Test {
    uint[] public array = [1, 2, 3];

    function removeLastElement() public {
        // Remove an array element
        array.pop();
    }

    function getArray() public view returns(uint[] memory) {
        return array;
    }
}

Keep this in mind along with the method for adding an array (push method).
