For a natural number, n, the function CC(n) is defined as follows:

In other words, CC(n) is the sum of cubes of all integers from 1 to n.

Given positive integers x and y, write a function that calculates the value of gcd(CC(x),CC(y)) . For example:

>> CC = @(n) sum((1:n).^3);

>> gcdCC = @(x,y) gcd(CC(x),CC(y));

>> gcdCC(5,10)

ans = 25

The following restrictions apply:

• The function should only have one (1) line of code, excluding the function start line.
• Semicolons (;) are considered end-of-line characters.
• Please suppress the function end line. Keyword 'end' is not allowed.
• Regular expressions are not allowed.
• Only 'pure' matlab functions/commands are allowed (no java, no python).
