You've been sucked into a computer! In this foreign, virtual landscape you see a glowing humanoid shape yelling in your direction. "HEY You! Your state seems to be idle. Come help us repair the corruption in this spreadsheet - if we don't hurry, we'll have to display a pinwheel cursor!"
The spreadsheet consists of rows of seemingly-random numbers. To make sure the recovery process is on the right track, they need you to calculate the spreadsheet's checksum.
For each row, determine the difference between the largest value and the smallest value; the checksum is the sum of all of these differences.
Here's an example of a spreadsheet:
var data = [
[2, 3, 7, 8],
[0, 1, 3],
[9, 2, 8, 3]
]- The first row's largest and smallest values are 2 and 8, their difference is 6.
- The second row's largest and smallest values are 0 and 3, their difference is 3.
- The third row's difference is 7.
In this example, the spreadsheet's checksum would be 6 + 3 + 7 = 16.
Create a function to find the checksum of the following.
var data = [
[409, 194, 207, 470, 178],
[454, 235, 333, 511, 103],
[474, 293, 525, 372, 408],
[428, 4321, 2786, 6683, 3921],
[265, 262, 6206, 2207, 5712]
]
