Question

The algorithm of Euclid computes the greatest common divisor (GCD) of two integer numbers a and b. The following pseudo-code is the original version of this algorithm. 

Algorithm Euclid(a,b)
Require: a, b ≥ 0
Ensure: a = GCD(a, b)
    while b ̸= 0 do
        t ← b
        b ← a mod b
        a ← t
end while
return a

We want to estimate its worst case running time using the big-Oh notation. Assuming the Euclidian division of two integers of n bits is executed in O(n^2), give a big-Oh notation of the worst-case running time of the algorithm Euclid.
