WebView code for the Extended Euclidean Algorithm (recursive) Just like in the non-recursive version, notice that the Python code returns multiple variables, whereas the C++ code uses global variables that you can call from your main function. The if statement is for the case when b=0 (e.g. when we call it like xgcd (some number, 0 )). WebOne trick for analyzing the time complexity of Euclid's algorithm is to follow what happens over two iterations: a', b' := a % b, b % (a % b) Now a and b will both decrease, instead of only one, which makes the analysis …
