这个测试样例这么挫比的吗，帖一下我的第二题代码 import sys lines = sys.stdin.readline() l = list(map(int, lines.strip().split())) left_num = sum(l) dp = [[0, ] * len(l) for _ in range(len(l))] for i in range(len(l)):     if len(l) % 2 == 0:         dp[i][i] = -l[i]     else:         dp[i][i] = l[i] for s in range(1, len(l)):     for i in range(len(l)-s):         j = i+s         dp[i][j] = max(dp[i][i] - dp[i+1][j], dp[j][j] - dp[i][j-1]) # print(dp) if len(l) % 2 == 1:     print("Yes") if dp[0][len(l)-1] >= 0 else print("No") if len(l) % 2 == 0:     print("Yes") if dp[0][len(l)-1] <= 0 else print("Yes")
