You are given two strings A and B. Find the index of the first occurrence of A in B. If A is not present in B, then return -1.
For Example:
A = “bc”, B = “abcddbc”.
String “A” is present at index 1, and 5(0-based index), but we will return 1 as it is the first occurrence of “A” in string “B”.
Follow Up:
Can you solve this in linear time and space complexity?
Problem approach
you can do it with brute-force approach which has complexity of O(n2). But I used sliding window with complexity of O(n)
