可以自定义模板


如上是我自定义的模板

使用enumerate() 可以很好的提高运行速度
如下两数相加的例子中,可以大大提高运行速度,当然这少不了哈希表的配合

# leetcode submit region begin(Prohibit modification and deletion)
class Solution(object):
    def twoSum(self, nums, target):
        hashmap = {}
        for ind, num in enumerate(nums):
            hashmap[num] = ind
        for i, num in enumerate(nums):
            j = hashmap.get(target - num)
            if j is not None and i != j:
                return [i, j]
# leetcode submit region end(Prohibit modification and deletion)
