Answer:
Maintenance Phase
Explanation:
One of the concepts employed in project management for describing stages involved when carrying out an information system development project is the systems development life cycle (SLDC). The cycle which starts from carrying out a feasibility study and ends in maintenance is a highly used conceptual model. There are 5 major stages or phase and they are the; Requirement Phase, Design Phase; Implementation Phase, Test Phase, and the Maintenance phase. The maintenance phase comes when testing has been complete and all enhancement and modifications have already been developed, and the system is operating.
Answer:
- import sys
-
- def fibonacci(n):
- if(n == 0 or n == 1):
- return n
- else:
- return fibonacci(n - 2) + fibonacci(n-1)
-
- num = int(sys.argv)
- output = ""
-
- for i in range(1, num+1):
- output += str(fibonacci(i)) + " "
-
- print(output)
Explanation:
Firstly, we import sys module as we need to accepts n as command line argument (Line 1).
Next, create a function fibonacci takes take one input n (Line 3). If the n is zero or one, return the n itself (Line 4-5). Otherwise, the program shall run the recursive call to the fibonacci function itself by putting n-2 and n-1 as function argument, respectively (Line 6-7).
After that, use the sys.argv to get the command line argument and assign the value to num (Line 9).
Use a for loop to generate the output string by progressively calling the fibonacci function and join the return result to the output string (Line 12-13).
At last print the output string (Line 15).
