This problem can be solved using dynamic programming. The idea is to calculate the number of unique BSTs for each number from 1 to n, and use these results to calculate the number of unique BSTs for larger numbers.

Here are the steps to solve this problem:

1. Create an array dp of size n+1, and initialize all elements to 0. dp[i] will store the number of unique BSTs with i nodes.

2. Set dp[0] and dp[1] to 1, because there is only one unique BST with 0 or 1 node.

3. For each number i from 2 to n

3. For each number i from 2 to n

Given an integer n, return the number of structurally unique BST's (binary search trees) which has exactly n nodes of unique values from 1 to n. Example 1:Input: n = 3Output: 5Example 2:Input: n = 1Output: 1 Constraints:1 <= n <= 19
