Product of an Array

You are given an integer array $A$ of size $N.$ Your task is to find and return an integer value representing the product of all the elements in the array.

Input Specification:

input$1$ : An integer array $A$

input$2$ : An integer value $N$ representing the size of the array

Output Specification:

Return an integer value representing the product of all the elements in the array.

Example $1$:

input$1$: $\{2,4,6,8\}$

input$2$: $4$

Output: $384$

Explanation:

Here, the array is $\{2,4,6,8\}$ and when all the elements are multiplied by each other $*6*8=384)$ the product obtained is $384.$ Hence, $384$ is returned as the output.

Example $2$:

input$1$: $\{1,2,3,4,5\}$

input$2$ : $5$

Output : $120$

Explanation:

Here, the array is $\{1,2,3,4,5\}$ and when all the elements are multiplied by each other $2**3**4**5=120)$ the product obtained is $120.$ Hence, $120$ is returned as the output.
