Iterative interleaving of strings X46901
The interleaving of two strings x and y is a string that contains all characters of x and y and preserves the relative order of the characters in both x and y. For example, the interleaving of abc and xyz is axbycz. Write a program that prints the interleaving of every given pair of strings.
Define and use an iterative function
interleaving(x,y)
that returns the interleaving of two strings x and y.
Interface
| C++ | string interleaving(string x, string y); |
| Python | interleaving(x, y) # returns str |
interleaving(x: str, y: str) -> str |
Input
The input consists of several pairs of strings.
Output
Print the interleaving of every given pair of strings.
