Tile pyramids on top of each other!
The task
Given a positive integer as input, output tiled pyramids of this height.
How?
Let's say the inputted integer was n. From there, we output n lines of output, each having:
- A decreasing indentation of spaces starting with
n-1spaces and ending with0spaces - An increasing number of the symbol
/starting with1symbol and ending withnsymbols - An increasing number of the symbol
\starting with1symbol and ending withnsymbols
For example, with an input of 4, the output should be the following:
/\
//\\
///\\\
////\\\\
Rules
- You may output an optional newline after the required output
- Input will always be a positive integer
- This is code-golf, so lowest byte-count for each language is the winner
Test cases
Input: 1
Output:
/\
Input: 7
Output:
/\
//\\
///\\\
////\\\\
/////\\\\\
//////\\\\\\
///////\\\\\\\
Input: 11
Output:
/\
//\\
///\\\
////\\\\
/////\\\\\
//////\\\\\\
///////\\\\\\\
////////\\\\\\\\
/////////\\\\\\\\\
//////////\\\\\\\\\\
///////////\\\\\\\\\\\

Sue me. It works.
set n to text returned of (display dialog "" default answer "") as number
set o to ""
repeat with i from 1 to n
repeat (n-i) times
set o to o&" "
end repeat
repeat i times
set o to o&"/"
end repeat
repeat i times
set o to o&"\\"
end repeat
set o to o&"\n"
end repeat

->n{(1..n).map{|i|" "*(n-i)+?/*i+?\\*i}*$/}
->n{ } # lambda
(1..n).map{|i| } # map over 1 to n
" "*(n-i)+?/*i+?\\*i # spaces plus / plus \
*$/ # join with newline
The special global variable $/ is initialized to newline by default, which is shorter than ?\n or "\n".
From globals.rdoc:
$/The input record separator, newline by default. Aliased to
$-0.
