Two Sum -Python解題

困難度:Easy

題目: 找出兩個數字的索引相加會等於目標數字。

Given an array of integers nums and an integer target, return indices of the two numbers such that they add up to target.

You may assume that each input would have exactly one solution, and you may not use the same element twice.

You can return the answer in any order.

Example 1:

Input: nums = [2,7,11,15], target = 9

Output: [0,1]

Output: Because nums[0] + nums[1] == 9

we return [0, 1].

Example 2:

Input: nums = [3,2,4], target = 6

Output: [1,2]

Example 3:

Input: nums = [3,3], target = 6

Output: [0,1]

Inline code has back-ticks around it.

class Solution:
    def twoSum(self, nums, target):
        for i in range(0,len(nums)):
            for j in range(i+1,len(nums)):
                a = nums[i]+nums[j]
                if a == target:
                    return [i,j]
