Показать описание
One of the most frequently asked coding interview questions on Dynamic Programing on Array in companies like Google, Facebook, Amazon, LinkedIn, Microsoft, Uber, Apple, Adobe etc.

LeetCode : Longest Palindromic Substring

Question Given an unsorted array of integers, find the length of longest increasing subsequence.

Example:

Input: [10,9,2,5,3,7,101,18]

Output: 4

Explanation: The longest increasing subsequence is [2,3,7,101], therefore the length is 4.

This could have been solved in O(n) using DP approach. O(n^2) is through brute force approach.

Half cooked explanation, you can do better. I don't think any interviewer will be happy with this mugged up solution. Not trying to discourage you by any means!!
