Calculate the number of grains of wheat on a chessboard given that the number on each square doubles.

There once was a wise servant who saved the life of a prince. The king promised to pay whatever the servant could dream up. Knowing that the king loved chess, the servant told the king he would like to have grains of wheat. One grain on the first square of a chess board, with the number of grains doubling on each successive square.

There are 64 squares on a chessboard (where square 1 has one grain, square 2 has two grains, and so on).

• How many grains were on a given square?
• Total number of grains that can exist on the chessboard given the condition.

• answerwer should be a BigInt value.
• Both function is given to you separate and you should write code in both functions.

• How many grains were on a given square?
• Total number of grains that can exist on the chessboard given the condition

const totalGrains = () => {
	// Code here

	return
}

const grainsOn = (input) => {
	// Code here

	return
}

console.log(`Grains on 5th square: ${grainsOn(5)}`)
console.log(`Total grains upto 5th square: ${totalGrains(5)}`)
