Input: nums = [1,3,5,4,7] Output: 2 Explanation: The two longest increasing subsequences are [1, 3, 4, 7] and [1, 3, 5, 7].

11 нояб. 2024 г. · Explanation: The length of the longest increasing subsequence is 4, and there are 2 longest increasing subsequences of length 4, i.e. {1, 3, 4, ...

Let us take a new array ct[ ] to calculate the count and initialize it to 1. Then ct[i] will be the count of the number of longest increasing subsequences ...

We conclude that the length of the longest increasing subsequence is 4 and the number of such subsequences is 1 (ending with the element 4 in the original ...

10 февр. 2024 г. · First we will search only for the length of the longest increasing subsequence, and only later learn how to restore the subsequence itself.

The longest increasing subsequence problem aims to find a subsequence of a given sequence in which the subsequence's elements are sorted in an ascending order.

Input: nums = [1,3,5,4,7] Output: 2 Explanation: The two longest increasing subsequences are [1, 3, 4, 7] and [1, 3, 5, 7].

Given an integer array arr, return the number of longest increasing subsequences. Notice that the sequence has to be strictly increasing.

Example 1: Input: nums = [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. Longest Increasing... · Increasing Triplet Subsequence · Number of LIS

There are other increasing subsequences as well, but we need the number of the longest ones. Hence the answer is 2.
