Data Interview Qs - String subsequences

Given two strings, String A and String B, write a function to return whether or not String A is a subsequence of String B. For String A to be a subsequence of String B it must be able to be derived from it by deleting some number of elements (without changing the order of the elements).

For example:

    
# Inputs:
    
String A = 'race'
    
String B = 'razcecar'
    

    
#Output: True
    
-------------
    
#Inputs:
    
String A = 'xyz'
    
String B = 'wyzx'
    

    
#Output: False
