    {
        int count=0;
        Scanner input=new Scanner(System.in);

        String str=input.nextLine();
        System.out.print("Enter letter to count: ");
        char ch=input.next().charAt(0);
        char arr[]=str.toLowerCase().toCharArray();
        for(int i=0;i<arr.length;i++){
            if(arr[i]==ch){
                count++;
            }
