	rep(i, 1, n) sum[i] = sum[i - 1] + (a[i] = rd());
	c[0][0] = 1;
	rep(i, 1, sum[n]) {

	}
	dp[0][0] = 1;
	rep(i, 0, n - 1)

			rep(k, j + 1, sum[i + 1] - 1) 
				rep(x, max(0, a[i + 1] - (k - j)), min(a[i + 1] - 1, sum[i + 1] - k - 1))
					add(dp[i + 1][k], 1ll * dp[i][j] * c[k - j - 1][a[i + 1] - x - 1] % mod);
		}
	int ans = 0;
	rep(i, 0, sum[n]) add(ans, dp[n][i]);
	printf("%d\n", ans);
	return 0;
}

这程序好像有点Bug,我给组数据试试?
