How to print a filled rectangle in Scala? -


print filled rectangle, filling // specified number of columns , rows of character inchar, // surrounded border made of character edgechar.

i'm confused understand want make multiple loops. have far nested loop outer loop number of columns , inner loop number of rows. i'm confused how print specific number of dashes , +s , loop content. , how , width , height come play

for (k=1; k <= columns;  columns >= k++) {   (i = 1; <= rows >= i++) {     println(edgechar)     //println(+-)   }    (i = 1; <= rows; i++){     (j)       println(edgechar)     }     (j = 1; j <= columns; j++){       println(inchar)     }     (k, k<=columns+2;k++){       println(edgechar)

this being scala, want map , play lists rather loops. here's working example (paste in scala repl):

val ec="@" val cc="x" val cols=8 val rows=5  ((ec*(cols+2)) +: range(0,rows).map( _ => ec+cc*cols+ec) :+ (ec*(cols+2)) ).mkstring("\n")

this results in:

res22: string = @@@@@@@@@@ @xxxxxxxx@ @xxxxxxxx@ @xxxxxxxx@ @xxxxxxxx@ @xxxxxxxx@ @@@@@@@@@@

bash - Performing variable substitution in a string -

i have string contains use of variable, , i'd substitute variable's value string. right best have is #!/bin/bash foo='$name; echo bar' name="the name" expanded="$(eval echo "$foo")" echo "$expanded" which has obvious defects: prints the name bar while i'd print the name; echo bar instead of eval can bash's regex matching bash's string replacement: foo='$name; echo bar' name="the name" [[ "$foo" =~ \$([[:alnum:]]+) ]] && s="${!bash_rematch[1]}" && expanded="${foo/\$${bash_rematch[1]}/$s}" echo "$expanded" name; echo bar
