This question is about finding the function body for a function wrap based on the input$/$output behavior of the function wrap. Consider the following LAMBDA call and its output:

$))))$

wrap$(r_1,$err$1),$

wrap$(r_2,$err$2),$

wrap$(SEQUENCE(r_3),$err$3),$

$(($ wrap$(r_4,$err$4)(($ show

output:

$\backslash$table$[[,1$err $2,$err $4],[$nothing$,$nothing,$2$nothing$]]$

This output shows you the result of the LAMBDA call, which includes the results of $5$ wrap calls. Based on the input$/$output behavior of the wrap function, find its body.

The function wrap uses the signature LAMBDA$(r,m,$BODY, where $r$ and $m$ are the formal arguments. BODY must be the most straightforward and shortest wrap implementation consistent with the given input$/$output behavior. Don't use any blanks in BODY. There is only one correct answer for BODY. Test your solution with Excel $365$ by defining function wrap in the name manager.
