echo "Enter the array";
# To read the input from keyboard
read n
IFS="," #delimiter declartion.
a=0
# Declared new empty array for storing the result which does not contain the zero in it.
declare -a resultArray=()

#Splitting the string using delimiter ','
read -ra IN <<<"$n"

#Iterating the array one by one to find out the zero
for i in "${IN[@]}";
do
  
#Comparing the each element of array with zero if not equal to zero then storing into new array i.e resultArray
if [[ $i != $a ]] #Converting string element into integer
then
resultArray+=($i)
fi
done
#Printing the resultant array without zero in it
echo "${resultArray[*]}"
