function bubble-sort {
	new_array=(${array[@]::${#array[@]}-1}) #all elements except the last one
	for i in "${!array[@]}"; do
		switch=false;
		for j in "${!new_array[@]}" ; do

				aux=${array[j]}
				array[j]=${array[j+1]}
				array[j+1]=$aux
				switch=true;
			fi;
		done;
		if [ $switch = false ]; then 
			break; 
		fi;
	done;
}

#Validation to fit criteria
if [ "$#" != "1" ]; then echo $ERROR; exit 1; fi; #wrong input
if [[ ! "$1" =~ "," ]]; then echo $ERROR; exit 1; fi; #wrong format

array=($(echo $@ | tr ", " " "))

if [ "${array[0]}" == "" ]; then echo $ERROR; exit 1; fi; #empty input
if [ "${#array[@]}" == "1" ]; then echo $ERROR; exit 1; fi; #not a list

bubble-sort array
arrayString=${array[@]}
echo "${arrayString//" "/", "}"
