Complexity exercise

1 Complexity myFunction(n) { if (n0) return myFunction (n/2) + f1(n); return myFunction(n/2) + f2(n); 1. What is the time complexity of myFunction, if f1 and f2 are constant time? If they are linear? 2. How can myFunction be rewriten in order to improve its performance? What is the complexity of this second version of the function, in the same conditions for f1 and f2 (constant, then linear)
