How to realize the Sum of two numbers by Java

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.
