Write a program in $C$ to count the total number of elements that have a duplicate in a list$/$array$.$ For example, in the array $(1,3,4,1,3,6),$ there are two elements that have duplicates, $1$ and $3.$ Therefore the program should print $2.$ For the array $(2,4,3,4,1,4),$ the program should print $1,$ since only one element has duplicates $($i$.$e$.4).$ Your program should first ask the user how many numbers are in the array. Then it should

prompt for each element of that array. Finally, it should output the number of items which

have duplicates as single integer. For example, this enters a $3-$element array $(1,1,8),$ which

only has one element with duplicates:

$[$prompt$]$ How big is the array?

$[$input$]3$

$[$prompt$]$ Enter element $1$:

$[$input$]1$

$[$prompt$]$ Enter element $2$:

$[$input$]1$

$[$prompt$]$ Enter element $3$:

$[$input$]8$

$[$output$]1$
