Question 1 There is only one supercell (number greater than all its neighbours) in this grid. If you exchange two digits of one of the numbers, there will be 4 supercells. Figure out which digits to swap.The digits to swap are the '6' and '1' in the number 62,871. Original Number: 62,871 New Number: 12,871 Reasoning: Initially, 62,871 is the only supercell. By swapping its digits to make it 12,871, it becomes much smaller and is no longer a supercell. However, this change causes its four neighbors—39,344, 23,609, 45,306, and 50,319—to all become larger than their neighbors, turning them into a new set of 4 supercells.
