Concatenate Strings Alphabetically

Two string values S1 and S2 are passed as the input. The program must concatenate them depending on which string comes first in the alphabetical order.

Example 1:

Input:
apple
orange
Output:
appleorange

Example 2:

Input:
zoo
tiger
Output:
tigerzoo

printf(“%s%s”,second,first);
