ENG 2139 ASSIGNMENT No 2 ON RECURSIVE FUNCTIONS Given is a sequence of the followngatn:,2,6, 24,120, 720,.. a) First wrte recursive equations for the above sequence, which you will name as Hekima Sequence" so that you can refer to it later. b) Write a C++ recursive function that can compute the "Hekima Sequence" of any unsigned long number. You should then call this recursive function from your main function in which you will request the user to input an unsigned long number of their choice, then you read it and pass it to the "Hekima Sequence" C++ recursive function. Your result will be displayed with a message You entered the number: 'value of n', and its "Hekima Sequence" is: 'the return value of the "Hekima Sequence C++ recursive function. [10 Marks] END
