	//!!!!!! trqbva funkciqta da e string, a ne void i da vrushta result

	//kak da proverq dali nqkoj masiv e prazen








	//zashto ne raboti
	//cout << result;

	// kak da izpechatam rezultata bez cikul



	//zashto ne moga na masiv da prisvoq stoinostta na string
	// \t ...ne raboti kato primera ako stoinostta na stringa e vkarana ot konzolata- tova normalno li e?
	// pri proverkata dali e empty ne mi izliza tekst: arr1/2= ....
