Problem:- Given two strings string1 and string2, remove those characters from first string(string1) which are present in second string(string2). Both the strings are different and contain only lowercase characters.

Input:
string1 = "computer"
string2 = "cat"
Output: "ompuer"
Explanation: After removing characters(c, a, t)
from string1 we get "ompuer".

Input:
string1 = "occurrence"
string2 = "car"
Output: "ouene"
Explanation: After removing characters
(c, a, r) from string1 we get "ouene".
