| 1. Write a program that performs the following. The user
inputs a number and then enters a series of numbers
from 1 to that number. Your program should determine
which number (or numbers) is missing or duplicated in
the series, if any. For example, if the user entered
5 as the initial number and then entered the
following sequences, the results should be as shown.
Input Sequence Output
---------------------- ---------------
1 2 3 4 5 Nothing bad
However, if 7 were the high number, the user
would see the results on the right for the following
number entries:
Input Sequence Output
---------------------- ---------------
1 3 2 4 5 Missing 6
Missing 7
And if 10 were the high number and the user
entered the numbers shown on the left, note the list
of missing and duplicate numbers:
Input Sequence Output
---------------------- ---------------
1 2 4 7 4 4 5 10 8 2 6 Duplicate 2 ( 2 times)
Missing 3
Duplicate 4 ( 3 times )
Missing 9

| Write a program using one dimensional array that accept five
values from the keyboard. Then it should also accept a
number to search. This number is to be searched if it among
the five input values. If it is found, display the message
“Search number is found!” otherwise, display “Search is lost”.
Example:
Enter 5 numbers: 10 15 20 7 8
Enter number to search: 7
Search number is found!
