Select the correct answer. Terrence has five columns of numbers in a spreadsheet. He's entered formulas at the end of each column to calculate the average of the
numbers. One of the averages seems implausibly incorrect. Which TWO of the following might be causing this?
The spreadsheet software isn't working correctly.
Terrence made a mistake while entering the formula.
Terrence should have entered the numbers in rows rather than columns.
Terrence entered one or more numbers incorrectly.
A formula can calculate an average only if there's also a formula to calculate the sum.

You will be given two character arrays of the same size, one will contain a number of ships. ships will move around the character array based on which way they are facing and the route they are on. routes are given in the other array. the route consists of '-' and '|' for straight paths, '\' and '/' for curves, and '+' for intersections. there are ships on these routes. ships always face a direction, '^' for up, '> ' for right, 'v' for down, and '< ' for left. any time the ships hit a '\' or a '/' it will turn as you would expect a ship to turn (e. g. a '^' that moves into a '/' will turn right). at an intersection, ships will always continue straight through. all ships move at the same speed, ships take turns moving and all ships move during one 'tick'. the one in the most top left goes first, followed by those to its right, then the ones in the next row. it iterates along the rows and then down the columns. each ship moves one space on its turn moving along the route. your function needs to return the position of the first collision between two ships and the number of ticks before the crash occurred.
