Define a function named one_each(...) which receives two strings ( not necessarily of the same length) and returns a string containing alternating characters in the two strings, starting with the first character of the first string, then the first character of the second string, etc, as many times as there are characters in the shortest string. The extra characters of the longer string are not considered.

As an example, the following code fragment:

print(one_each("abcd","ABCDEFGHIJK"))

should produce the output:

aAbBcCdD
