Find remaining letter after striking out using the last stroke out characters value - Java Quiz Question

Write a program to find the remaining letter after striking out using the last stroke out character's value. Character value is nothing but 1 for A, 2 for B and so on. To start with cancel out the first letter.

As shown below for COREJAVA, first C is cancelled since it is the first letter, then J is cancelled since it is fourth letter (3 (value of C) + 1) from C, followed by R which is 11th letter (10 (value of J) + 1) from J and so on.

Note: Do not count already cancelled characters while moving.

Input (Character array)	Output (Character)
['C', 'O', 'R', 'E', 'J', 'A', 'V', 'A']	`OREJAVA // Always Cancel First Character OREAVA // Move right by Last Cancelled Character Value ie. C or 3 OEAVA // Move right by Last Cancelled Character Value ie. J or 10 OEAV O*AV ****AV ***A // Repeat until only one character is present Output = A`
['D', 'O', 'T', 'N', 'E', 'T']	E
['H', 'I', 'B', 'E', 'R', 'N', 'A', 'T', 'E']	E
['P', 'E', 'R', 'L']	E
['D', 'A', 'B', 'C']	`ABC // Cancel First Character D AC // Move right by D(or 4) positions A** // Move right by B(or 2) positions Output = A`

	
		class FindRemainingLetterAfterStrikingOut2	
			{    public static void main(String s[])
    {
        char input[] = {'C', 'O', 'R', 'E', 'J', 'A', 'V', 'A'};
        System.out.println("The remaining letter is : " + getRemainingLetter(input));

    }
 
			

				public static char getRemainingLetter(char[] input) { 

				//Write code here to get the remaining letter after striking out as explained above. 

				} 

			}
