Help with infinite loop problem
1. The problem statement, all variables and given/known data:
My problem is an infinite loop when i press any other key other then Y or y in the while loop. what i want it to do is return to the normal script outside of it if pressing N or n or keep asking the same question if its any other button. Perhaps my knowledge and understanding of loops is inaccurate. But i have made it very similar to the lecture shown ones and it isnt working out very well. Thanks in advance.

2. Relevant commands, code, scripts, algorithms:

P.S. I am using cygwin in windows to do this script.

3. The attempts at a solution (include all code and scripts):
Code:
"4")
clear
echo Would you like to exit? [y/n]?
read answer
while [ "$answer" != "Y" ] || [ "$answer" != "y" ]; do
        case "$answer" in
        "Y" | "y")  clear; exit ;;
        "N" | "n")
                echo Press enter to continue
                read a ;;
        *)
                echo Invalid input
                echo Press enter to continue...
                read a
                ;;
        esac
        if [ $answer != "Y" ] || [ "$answer" != "y" ]; then
        echo "Press enter to continue..."
        read A
        fi
