1. Two Sum
Given an array of integers, return indices of the two numbers such that they add up to a specific target.
You may assume that each input would have exactly one solution, and you may not use the same element twice.
Example:
Given nums = [2, 7, 11, 15], target = 9
Because nums[0] + nums[1] = 2 + 7 = 9,
return [0, 1].
class Solution(object): def twoSum(self, nums, target): """ :type nums: List[int] :type target: int :rtype: List[int] """ if (len(nums) < 2): return temp={} for i in range(len(nums)): x = nums[i] if target-x in temp: return (temp[target-x], i) temp[x] = i
