Write compute$\_$sum$()\text{'}$s base case to output sum$\_$val, $\text{'}=\text{'},$ and val in one line with end$=\text{'}\text{'}$ if val is less than or equal to $1.$ def compute$\_$sum$($val$,$ sum$\_$val$)$:

sum$\_$val $+=$ val

# Your code goes here

else:

compute$\_$sum$($val $-1,$ sum$\_$val$)$

print$($f$\text{'}+\{$val$\}\text{'},$ end$=\text{'}\text{'})$

val $=$ int$($input$())$

compute$\_$sum$($val$,0)$

print$()$
