一、两数之和
#解法1
class Solution(object):
    def twoSum(self, nums, target):
        lens = len(nums)
        for i in range(0,lens):
            for j in range(i+1,lens):
                num1 = nums[i]
                num2 = nums[j]
                if (num1 + num2 == target):
                    # m = nums.index(num1)
                    # n = nums.index(num2)
                    lis = [i,j]
                    return (lis)
    twoSum(0,[4,3,2], 5)

#解法2
class Solution(object):
    def twoSum(self, nums, target):
        j = -1
        lens = len(nums)
        for i in range(1,lens):
            temp = nums[:i]
            if (target - nums[i]) in temp:
                j = temp.index(target - nums[i])
                break
        if j >= 0:
            lis = [j,i]
            return (lis)
    twoSum(0,[4,3,2], 5)
