Answer 1

According to the code provided above,

The newNumbers will get a map of integer values after conversion of float to int by toInt method.

Explanation:

• Here, we have array of float value elements in the variable numbers
• We have declared a new map variable newNumbers which has the statement to convert float to int values
• newNumbers = numbers.map(_.toInt)
• map function will get all values from the array numbers.
• And then converts all float values to int
• newNumbers = (2, 1, 3, 9, 2, 9, 1)

I hope the above information and explanation will help you out to understand!
