Valid Palindrome Ii

Lesson 105/115

DATA STRUCTURES • ALGORITHMS
Valid Palindrome IiTwo-pointer techniques involve using two indices that move independently across the string, often from opposite ends or in the same direction.
Time
O(N)
Space
O(1)
Key Principle 1
Useful for reversal and palindromes.
Key Principle 2
Pointers can move inward or outward.
Key Principle 3
Highly memory efficient.
