Validation should always go into the function. Or else you have to write the validation everytime you call it. Move it into the function.

This is the correct solution. But try doing it with loops.

| //using array function in the map methods | ||

| console.log(`Given input array is ${inputArray}`); |

Print before and after arrays. Also do not mutate the array. Take the output into a new array.
Do you think map function mutates the array or creates a new one?
