    !/bin/bash

    Read all lines into an array

    countries=() while IFS= read -r line; do countries+=("$line") done

    Define start and end indices (0-based)

    start=3 end=7

    Calculate length of slice

    length=$(( end - start + 1 ))

    Slice the array and print

    slice=("${countries[@]:start:length}")

    echo "${slice[@]}"

    my solution

    #!/bin/bash
declare -a array
i=0
#storing country names in the array
while read -r country; do
    array[$i]=$country
    ((i++))
done

for ((j=0;j<i;j++)); do
    if [[ $j -ge 3 ]] && [[ $j -le 7 ]]; then
        echo -n "${array[$j]} "
    fi
done | paste -sd ' '
