Recursion in Functional Programming

Contains

Report a typo

Implement contains, which takes non-negative integers $a$ and $b$ . It returns whether all the digits of $a$ also appear in order among the digits of $b$ . Given $a = 357$ and $b = 12345678$ the numbers in $a$ appear sequentially in the number $b$ , so the function returns True

There are many ways to solve this task, but please try to solve using recursion.

Sample Input 1:

357 
12345678

Sample Output 1:

True
