Perform the following tasks:

Write a function called mylncArray that takes a number $N$ as input and returns an array containing $N$ elements: $1,2,3,$dots,$N.$ Use this function and $N$ to construct a new

array $A.$

Write a function called myDecArray that takes a number $N$ as input and returns an array containing $N$ elements: $N,N-1,N-2,$dots,$1.$ Use this function and $N$ to construct a

new array $B.$

Write a function called mySumArray that takes two arrays as input and returns their sum. Use this function and arrays A and $B$ to construct a new array $C.$

Write a function called myMultArray that takes an array as input and constructs a new array whose $n-$th entry is given by $n$ plus $n$ times the $n-$th element the input array.

Use this function and the array $C$ to constructa new array $D.$

Construct $E$ to be one more that the sum of all elements in $D,$ using the built$-$in function called 'sum'.$|$
