LeetCode: 96. Unique Binary Search Trees
focalpoint 2021. 10. 13. 20:58class Solution:
def numTrees(self, n: int) -> int:
dp = [0] * (n+1)
dp[0] = 1
dp[1] = 1
for i in range(2, n+1):
count = 0
for j in range(1, i+1):
count += dp[j-1] * dp[i-j]
dp[i] = count
return dp[n]'Computer Science > Coding Test' 카테고리의 다른 글
