✍🏻 풀이

🎨 Go

package main

import (
	"bufio"
	"fmt"
	"os"
)

func main() {
	reader := bufio.NewReader(os.Stdin)
	writer := bufio.NewWriter(os.Stdout)
	defer writer.Flush()

	var n int
	fmt.Fscanln(reader, &n)

	var dp = make([]int, n+1)
	dp[0] = 1
	for i := 1; i < n+1; i++ {
		for j := 0; j < i; j++ {
			dp[i] += dp[j] * dp[i-j-1]
		}
	}
	fmt.Fprintln(writer, dp[n])
}

import sys

if __name__ == "__main__":
    n = int(sys.stdin.readline())
    dp = [0] * (n+1)
    dp[0] = 1
    for i in range(1, n+1):
        for j in range(0, i):
            dp[i] += dp[j] * dp[i-j-1]
    print(dp[n])
