Description

Given an array of integers, return indices of the two numbers such that they add up to a specific target

Demo Code

/*/*w  w  w.  j  a  v  a2 s  .co  m*/
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].
*/

var twoSum = function(nums, target) {

    for(let i=0; i<nums.length; i++) {
      for(let k=i+1; k<nums.length; k++) {

        if ((nums[i] + nums[k]) === target) {
             return[i, k];
          }
    }
  }
  return "No matches";
};

//Sam as above but it can have multiple correct answers
function twoSum(nums, target) {

    let temp = [];

    for(let i=0; i<nums.length; i++) {

        if ((nums[i] + nums[i+1]) === target) {
            temp.push([i, i+1]);
        }
        else {
          for (let k=0; k < nums.length; k++) {
            if(nums[i] + nums[k] === 0) {
              temp.push([i, k]);
            }
          }
        }
    }

    return temp;
}
