add(Param1, Param2) ->
    Param1 + Param2.

This just adds the two input numbers with the language’s normal arithmetic and returns the sum.

func add(param1, param2 int) int {
	return param1 + param2
}

add :: Num a => a -> a -> a
add param1 param2 = param1 + param2

public class Solution {
    public static int add(int param1, int param2) {
        return param1 + param2;
    }
}

(defun add (param1 param2)
  (+ param1 param2))

    return param1 + param2

fn add(param1: i64, param2: i64) -> i64 {
    param1 + param2

add_border() {
    local -n _pic="$1"
    local -n _outPic="$2"
    local _width=${#_pic[0]}
    local _border
    _border=$(printf '%*s' "$_width" '' | tr ' ' '*')

    local _line
    for _line in "${_pic[@]}"; do
        _outPic+=("*${_line}*")
    done
    _outPic+=("$_border")
}

This builds a new grid with a * border around every side. It adds a full top and bottom row, then wraps each existing row from left and right.
