1. Two Sum(兩數之和) —— Java
自己刷題,只是為了存下來,別吐槽
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].
classSolution { public int[] twoSum(int[] nums, int target){ int[] result = new int[2]; for(int i=0;i<nums.length-1;i++){ for(intj=i+1;j<nums.length;j++){ if(nums[i] + nums[j] ==target){ result[0] = i; result[1] = j; break; } } } return result; } }
