Consider a CSV, in the csv you're not allowed to have use "inferSchema", but manually devise a
way to infter the schema for the entire csv
Implement a way such that we can find datatype of each record in file by just looking at some
sample records without explicitly specifying schema.
Synopsis:
Given a function:
def SchemaConverter ([list of parameters]) : [return type] = {
function body
return [expr]
}
Implement the function as per given description, with schema inference to at least one type
such as Date or Time Type.
Input:
CSV
Output:
Schema of CSV.

I don't know why some people take issue with an Indian accent. I think it sounds just fine, even kind of adorable.

Sir, please help me with this problem which I encountered while practicing ....
Suppose we want to sort a list of numbers in ascending order:

One way to sort the list List(7, 3, 9, 2) is to sort the tail List(3, 9, 2) to obtain List(2, 3, 9).

The next step is to insert the head 7 in the right place to obtain the result List(2, 3, 7, 9).

This idea describes Insertion Sort:

def insertionSort(xs: List[Int]): List[Int] = xs match {
case List() => List()
case y :: ys => insert(y, insertionSort(ys))
}
Complete the definition insertion sort by filling in the blanks in the definition below:

Run

val cond: (Int, Int) => Boolean = \\ first blank
def insert(x: Int, xs: List[Int]): List[Int] =
xs match {
case List() => x :: \\ second blank
case y :: ys =>
if (cond(x, y)) x :: y :: ys
else y :: insert(x, ys)
}
insert(2, 1 :: 3 :: Nil) shouldBe (1 :: 2 :: 3 :: Nil)
insert(1, 2 :: 3 :: Nil) shouldBe (1 :: 2 :: 3 :: Nil)
insert(3, 1 :: 2 :: Nil) shouldBe (1 :: 2 :: 3 :: Nil)
