Check function name then write

import sys sys.setrecursionlimit(2000) input = sys.stdin.read def solve(N: int, S: str, w: list) -> int: if N == 0: return 0 dp = [[0] * N for _ in range(N)] for i in range(N): dp[i][i] = w[i] for length in range(2, N + 1): for i in range(N - length + 1): j = i + length - 1 if S[i] == S[j]: if length == 2: dp[i][j] = w[i] + w[j] else: dp[i][j] = dp[i+1][j-1] + w[i] + w[j] else: dp[i][j] = max(dp[i+1][j], dp[i][j-1]) return dp[0][N-1] if name == "main": data = input().split() if data: N = int(data[0]) S = data[1] w = list(map(int, data[2:])) result = solve(N, S, w) print(result)
