Write a program to take user input to Enter $10$ elements in an array and print the largest number.

Reverse an Array: Write a program where you initialize an array of integers; declare a second empty array of same size it should store all values from the first array in reversed order. Example: Input: $[1,2,3,4,5],$ Output $[5,4,3,2,1]$

Check for Duplicates: Write a program to take user input to initialize an integer array. Create a function to determine if this array of numbers contains any duplicate elements.

Example: Input: $[3,1,4,2,3],$ Output: True $($because the number $3$ appears more than once$)$

Find the Missing Number: Given an array $($Take user input$)$ of $n-1$ integers in the range from $1$ to $n,$ your task is to find the missing number that is not present in the arrray.

Example: Input: $[1,2,4,6,3],n=6,$ Output: $5($since $5$ is the missing number in the sequence from $1$ to $6)$

Calculate the Average: Write a program that calculates the average value of an array of numbers that is input by the user.

Example: Input: $1,2,3,4,5,$ Output: $3($the average of $1,2,3,4,$ and $5)$
