The class should provide the&nbsp;mathematical operations of&nbsp;addition, subtraction, multiplication, division, and exponentiation. It should also allow consecutive operations to be performed using method chaining.&nbsp;The <code>Calculator</code> class constructor should accept a number&nbsp;which serves as the&nbsp;initial value of <code>result</code>.</p>\n\n<p>Your <font face=\"monospace\"><code>Calculator</code>&nbsp;</font>class should have the following methods:</p>\n\n<ul>\n\t<li><code>add</code> - This method adds the given number <code>value</code> to the&nbsp;<code>result</code> and returns the updated <code>Calculator</code>.</li>\n\t<li><code>subtract</code> -&nbsp;This method subtracts the given number <code>value</code>&nbsp;from the&nbsp;<code>result</code> and returns the updated <code>Calculator</code>.</li>\n\t<li><code>multiply</code> -&nbsp;This method multiplies the <code>result</code>&nbsp; by the given number <code>value</code> and returns the updated <code>Calculator</code>.</li>\n\t<li><code>divide</code> -&nbsp;This method divides the <code>result</code> by the given number <code>value</code> and returns the updated <code>Calculator</code>.
