answer:Here is a Python program that uses dynamic programming to find the length of the longest increasing subsequence: ```python def longest_increasing_subsequence(nums): if not nums: return 0 dp = [1] * len(nums) for i in range(1, len(nums)): for j in range(i): if nums[i] > nums[j]: dp[i] = max(dp[i], dp[j] + 1) return max(dp) # Example usage: numbers = [10, 22, 9, 33, 21, 50, 41, 60, 80] print(longest_increasing_subsequence(numbers)) ``` This program works by maintaining an array `dp` where `dp[i]` is the length of the longest increasing subsequence ending at `nums[i]`. For each number in the list, it checks all previous numbers and updates `dp[i]` if it finds a smaller number that could be part of a longer increasing subsequence. Finally, it returns the maximum value in `dp`, which represents the length of the longest increasing subsequence. Note that this program has a time complexity of O(n^2), where n is the length of the input list. This is because it uses two nested loops to compare each pair of numbers in the list. However, it uses O(n) space to store the `dp` array. Alternatively, you can use a binary search approach to solve this problem with a time complexity of O(n log n). Here is an implementation: ```python def longest_increasing_subsequence(nums): if not nums: return 0 dp = [nums[0]] for num in nums[1:]: if num > dp[-1]: dp.append(num) else: i = binary_search(dp, num) dp[i] = num return len(dp) def binary_search(arr, target): left, right = 0, len(arr) - 1 while left < right: mid = (left + right) // 2 if arr[mid] < target: left = mid + 1 else: right = mid return left # Example usage: numbers = [10, 22, 9, 33, 21, 50, 41, 60, 80] print(longest_increasing_subsequence(numbers)) ``` This program maintains an array `dp` where `dp[i]` is the smallest tail of an increasing subsequence of length `i + 1`. It uses binary search to find the correct position to insert each number in `dp`. Finally, it returns the length of `dp`, which represents the length of the longest increasing subsequence.
