28. Implement strStr()

Easy

Implement strStr().

+ +

Given two strings needle and haystack, return the index of the first occurrence of needle in haystack, or -1 if needle is not part of haystack.

+ +

Clarification:

+ +

What should we return when needle is an empty string? This is a great question to ask during an interview.

+ +

For the purpose of this problem, we will return 0 when needle is an empty string. This is consistent to C's strstr() and Java's indexOf().

+ +

 

+

Example 1:

+ +
Input: haystack = "hello", needle = "ll"
+Output: 2
+
+ +

Example 2:

+ +
Input: haystack = "aaaaa", needle = "bba"
+Output: -1
+
+ +
