Replace every element with its previous element

Given an array of integers, replace each element in the array by the previous element.

Replace the first element by $-1.$

Write a function:

void replaceElements$($int array$[],$ int size$)$ that accepts an array and the size of the array.

Parameters:

array $=\{1,2,3,4\}$

size $=4$

Output

$-1123$

Explanation: Every element A$[$i$]$ is replaced by $A[i-1].$ And the first element will be $-1,$ as the first element doesn't have any previous element.

You only need to write the function. A main program will be provided which will call your function, and print the array contents after your function ends.
