Set numbers$\_$set$1$ contains $28.$ Set numbers$\_$set$2$ contains three integers read from input. Perform the following tasks:

Read the next integer from input and add the integer to numbers$\_$set$1.$

Update numbers$\_$set$1$ with numbers$\_$set$2.$

Remove one random element from numbers$\_$set$2.$numbers$\_$set$1=\{28\}$

numbers$\_$set$2=$ set$()$

numbers$\_$set$2.$add$($int$($input$()))$

numbers$\_$set$2.$add$($int$($input$()))$

numbers$\_$set$2.$add$($int$($input$()))$

numbers$\_$set$2.$add$($int$($input$()))$

numbers$\_$set$1.$update$($numbers$\_$set$2)$

numbers$\_$set$2.$pop$()$

print$($f$\text{'}$numbers$\_$set$1$: $\{$sorted$($numbers$\_$set$1)\}\text{'})$

print$($f$\text{'}$numbers$\_$set$2$ size: $\{$len$($numbers$\_$set$2)\}\text{'})$
