Coding problem1

1. Print Unique Elements from an Array

Given an array of integers, print all the elements that appear only once in the array.

Problem approach

I created a frequency map (using a HashMap/JavaScript object) to keep track of how many times each element appears in the array.
I traversed the array once, and for each element, I incremented its frequency in the map.
After building the frequency map, I looped through it and printed all the elements whose frequency was exactly 1.
