The laguage to be done is in C. Thanks but i have no idea how to work with this problem.

Create a program in Arduino that input five numbers between 10 and 100, inclusive. As each number is read, display it only if it's not a duplicate of a number already read. Display the complete set of unique values entered after the user enters each new value. Use one array to store elements and the function "investigar (" to prove the number is not in the array. See the example below: Enter number: 11 Enter number: 85 11 85 Enter number: 26 11 85 26 Enter number: 11 11 has already been entered 11 85 26 Enter number: 41 11 85 26 41
