• URL : https://www.hackerrank.com/challenges/staircase/problem

• Consider a staircase of size n = 4:

  1 2 3 4

  # ## ### ####

• Observe that its base and height are both equal to n, and the image is drawn using # symbols and spaces. The last line is not preceded by any spaces.

• Write a program that prints a staircase of size n.

• Function Description
  • Complete the staircase function in the editor below. It should print a staircase as described above.
  • staircase has the following parameter(s):
  • n: an integer
• Input Format
  • A single integer, n, denoting the size of the staircase.
• Constraints
  • 0 <= n <= 100
• Output Format
  • Print a staircase of size n using # symbols and spaces.
• Note: The last line must have 0 spaces in it.

문제풀이

• n이 주어지면 오른쪽 정렬이 된 ‘#’ 모양의 계단을 만드는 문제
• (n - i)는 ‘ ‘공백으로, i는 ‘#’로 출력하면됨
• 주의할점은 print할때 sep =’‘을 주어야 한다는것
