This article introduces the relevant knowledge of "how to achieve the sum of two numbers in Java". In the operation of actual cases, many people will encounter such a dilemma, so let the editor lead you to learn how to deal with these situations. I hope you can read it carefully and be able to achieve something!

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].

Title:

Given a sequence of integers, find out the two numbers in which the sum is a specific value.

You can assume that there is only one answer for each input, and the same element cannot be reused.

Example:

Given nums = [2,7,11,15], target = 9

Because nums [0] + nums [1] = 2 + 7 = 9

So return [0,1]

Create a dict to store the data idx

Class Solution: def twoSum (self, nums, target): ": type nums: List [int]: type target: int: rtype: List [int]"d = {} for I in enumerate (nums): if target-num in d: return [d [target-num]] I] d [num] = I "how Java achieves the sum of two numbers" ends here.
