WebA simple and sufficient test for the absence of a dependence is the greatest common divisor (GCD) test. It is based on the observation that if a loop carried dependency exists between X[a*i + b] and X[c*i + d] (where X is the array; a, b, c and d are integers, and i is the loop variable), then GCD (c, a) must divide (d – b). WebFeb 3, 2011 · The best way to find the gcd of n numbers is indeed using recursion.ie gcd (a,b,c)=gcd (gcd (a,b),c). But I was getting timeouts in certain programs when I did this. The optimization that was needed here was that the recursion should be solved using fast matrix multiplication algorithm. Share. can you homeschool in california
