Note python has this really weird error if you define local variable in a function same name as the global variable, program will promptUnboundLocalError. child class object overrides parent class methods input: classfruit:defprint(self):print('a')defeat(self):print('b')classapple(fruit):defpr...
Astable sortis one where the initial order of equal elements is preserved. Some sorting algorithms are naturally stable, some are unstable. For instance, the merge sort and the bubble sort are stable sorting algorithms. On the other hand, heap sort and quick sort are examples of unstable sorti...
Merge Sort example Divide and Conquer Strategy Using the Divide and Conquer technique, we divide a problem into subproblems. When the solution to each subproblem is ready, we 'combine' the results from the subproblems to solve the main problem. Suppose we had to sort an array A. A subprobl...
