            if i + j >= n-1:

            else:
                print(" ",end='')
        print('\n')


staircase(4)

What I have tried:

mariostairs <- function(n){
      for (i in 0:n){
        for (j in 0:n){
          if (i+j >= n-1){
            print('x')
          }else{
            print('')
          }
        }
      }
    }

OK, and the question would be .... ?

It works for python, how would it be coded in r studio?

Dave Kreskowiak 11-Oct-22 17:26pm

You're making the assumption that print in R works the exact same way as it does in Python. That is not the case. You might want to look at cat in R.

Keep in mind, that you cannot just convert the code line-by-line and expect it work. R and Python work very differently from each other.

I will give you a hint though, you only need one loop to do this.

Kevin Thomas Oct2022 11-Oct-22 21:19pm

mariostairs <- function(n){
for (i in 1:n) {
cat('x',sep='\n')
}
}

this is the best I can come up with, how can i add an x to each row?

First, you don't need that "sep="\n"" thing at all. Next, you need to build a string of 'x's, and do it without a loop.

Mind you, I don't know R. I've never used it.

I don't understand, can you just show me?

I'm not doing your homework for you.

Hint: Look in the built in functions for building a string of repeating characters.

I figured it out thank you for your help

Solution 1

mariostairs <- function(n){
      for (i in 1:n) {
          cat(strrep('x',i),sep='\n')
        }
      }
    
     
    
      
      
    
          
     mariostairs(4)
