Fullstack Developer

You are given a string S. Your task is to process the string and identify all characters that appear exactly once.

From these unique characters, you must construct and return a new string. The characters in this new string must be ordered according to their first appearance in the original input string S.

If no character in the string S appears exactly once, you should return an empty string.

Write a program in Golang that prints 'Hello World' alternately 10 times using goroutines and channels.

You are given an array of integers. Your task is to write a program that splits this array into exactly four parts (or quarters).

The division rule is as follows:

Calculate the base size for each part by dividing the total number of elements, N, by 4 using integer division (part_size = N / 4).

The first three parts will each contain part_size elements.

The fourth part will contain all the remaining elements. This means if N is not perfectly divisible by 4, the last part will be larger than the others.

If the array has fewer than four elements, some of the first three parts may be empty.
