USE C# PLEASE!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

1. create unsigned integer array of 5000 elements. Example: const int size = 5000; uint[] factorial = new uint[size]; 2. create an variable for store last element index in array to know the most left element whith value 3. using do...while loop for enter interact procedure do { - set array elements to 0. - ask the user to enter number for compute factorial or -1 to exit program. - take the number to compute factorial by passing array and number to "ComputeFactorial" mehtod. // ComputeFactorial(?, ?, ?); - Display result to screen by call "Display" method. } while(number equal or not to -1)

static void ComputerFactorial( ? , ? , ?) { - set first element in result array to 1. (index 1 or index N-1) - set last_element index variable to 1. - set carray to 0; - apply simple factorial formula, N! = 1 * 2 * 3 * 4...... * N-1. - two loops to control the computation sequence outer loop: for how many mutiply operation for compute factorial number (index should begin with 2) { inter loop: compute factorial number and store the result into factorial array { - using factorial formula to compute one element result = element of array * outer loop index value + (uint) carry; - you need to check the result for 6 digits or beigger (it is check for carry or not) if(result > 999999) { -you need to compute carray. -compute correct value to store in the current element of array } else { -store result into the current element of array. -set the carry to 0; } } if you still have carry value (carry is greater then 0) { -increment last_element index by 1. -store carry to last_element in factorial array; -set carry to 0; } decrement last_element by 1. } }
