What is the order of growth of the following algorithm?

Based on the size of the input array what growth equation should we see? (Eg, Linear, Quadratic, Log)

Algorithm NegBeforePos(A[0..n 1]) //Puts negative elements before positive (and zeros, if any) in an array //Input: Array A[0.n - 1] of real numbers //Output: Array ??..n-1] in which all its negative elements precede nonnegative while i
