#2089 - Find Target Indices After Sorting Array

Easy • View on LeetCode • View on GitHub

Problem Description

You are given a 0-indexed integer array nums and a target element target.

A target index is an index i such that nums[i] == target.

Return a list of the target indices of nums after sorting nums in non-decreasing order.

If there are no target indices, return an empty list. The returned list must be sorted in increasing order.

Solution

/**
 * @param {number[]} nums
 * @param {number} target
 * @return {number[]}
 */
var targetIndices = function(nums, target) {
  const result = [];

  nums.sort((a, b) => a - b);

  for (let i = 0; i < nums.length; i++) {
    if (nums[i] === target) {
      result.push(i);
    }
  }

  return result;
};
