Find The Sum - Uncommon Alphabets - Uppercase Given two char arrays input1[] and input2[ ] which contains only upper case alphabets,

Step 1: Extract the alphabets which are present only in any one of the array.

(Uncommon alphabets)

Step 2: Get the ascii values of all the extracted alphabets.

Step 3: Calculate the sum of those ascii values, lets us call it as sum1 and calculate

single digit sum for sum1

ile keep adding the digits of sum1 until you arrive at a single digit.

Step 4: Return the single digit as output.

Note :

1. Array size ranges from 1 to 15.

2. All the array elements are upper case alphabets.

Example 1:

input1: ('A', 'B', 'C'}

input2: ('B', 'C')

output: 65 => 6 + 5 = 11

==> 1 + 1 = 2​
