Given an array of integers that is alreadysorted in ascending order, find two numbers such that they add up to a specific target number. The function twoSum should return indices of the two numbers such that they add up to the target, where index1 must be less than index2. Note: Your ...
Output:[1,2] Explanation:The sum of 2 and 7 is 9. Therefore, index1 = 1, index2 = 2. We return [1, 2]. Example 2: Input:numbers = [2,3,4], target = 6 Output:[1,3] Explanation:The sum of 2 and 4 is 6. Therefore index1 = 1, index2 = 3. We return [1, 3]....
Explanation: The sum of 2 and 7 is 9. Therefore index1 = 1, index2 = 2. 方法一: int* twoSum(int* numbers,intnumbersSize,inttarget,int*returnSize) {*returnSize =2;int*Array =NULL;for(inti =1; i < numbersSize; i++) {for(intj =0; j < i; j++) ...
