    • If it is true, calculate the value of “a”, “b”, “c”, “d”, and “e” using the formula.
    • Check whether the sum of "d” and “e” is greater than “9”,
      • If it is true, check whether the year is either “1954” or “1981” or “2049” or “2076”,
        • If it is true, subtract 7 days from “d’ value and print the date of Easter one week too late on April.
      • Otherwise, print the date of Easter on April.
      • Otherwise, check whether the year is either “1954” or “1981” or “2049” or “2076”,
