  1. make a vector to store the sum of the values
  2. start from the last element of both the array
    3 initially the carry is0
  3. take addition of values at corresponding index and add carry
    not if the sum of digits is greater than 9
    then take sum%10 and add it to the vector
    and carry = sum/10
    do this until both array are traversed completely
