749. 约翰的后花园
约翰想在他家后面的空地上建一个后花园，现在有两种砖，一种3 dm的高度，7 dm的高度。约翰想围成x dm的墙。如果约翰能做到，输出YES，否则输出NO。
Example 1:
Input : x = 10
Output : "YES"
Explanation :
x = 3 + 7:That is, you need one batch of 3 dm height bricks and one batch of 7 dm height bricks.
Example 2:
Input : x = 5
Output : "NO"
Explanation:
John can not enclose a high 5 dm wall with 3 dm height bricks and 7 dm height bricks.
Example 3:
Input : x = 13
Output : "YES"
Explanation :
x = 2 * 3 + 7:That is, you need two batch of 3 dm height bricks and one batch of 7 dm height bricks.
X是一个整数，取值范围为 [3, 1000]。
class Solution: """ @param x: the wall‘s height @return: YES or NO """ def isBuild(self, x): # write you code here if x%3 == 0 or x%7%3 == 0: return ‘YES‘ elif x%3 == 1: if x>7: return ‘YES‘ return ‘NO‘
