$4\mathrm{.}3\mathrm{.}4$: Advanced while loop examples.

Start

Strings item$\_$of$\_$interest and input$\_$item are read from input. Integer expected$\_$count is initialized with $1.$ Write a while loop that iterates until inputitem is equal to 'Done'. In each iteration of the loop

Increment expected$\_$count if input$\_$item is equal to item$\_$of$\_$interest.

Read string input$\_$item from input

Click here for example

Note: Assume that input has at least two strings

$1$ item$\_$of$\_$interest $=$ input $()$

$2$ input$\_$item $=$ input $()$

$4$ expected$\_$count $=1$

$6$ I$\text{'}\text{'}\text{'}$ Your code goes here $\text{'}\text{'}.$

$8$ print$($f$\text{'}\{$item$\_$of$\_$interest$\}$ occurs $\{$expected$\_$count $\}$ time$($s$).\text{'})$
