Use the abs method, if </ b>!

1. How to program

``````def close_far(a,b,c) #---❶
x_mar = (a-b).abs
y_mar = (a-c).abs
z_mar = (b-c).abs
if (x_mar == 2 && z_mar >= 3) || (y_mar == 2 && z_mar >= 3) #---❷
puts "True"
else
puts "False"
end
end
``````

This time I made 3 integers.

❶: The abs method is used to return the absolute value regardless of the positive / negative relationship and assign each to a variable. ❷: This time, "the difference between" a "and" b "is 2 or the difference between" a "and" b "is 2 And"b"When"c”の差が3」Whenしています。下記のようにコーディングするこWhenも可能ですが、上記のように「()When||(OR)When&&(AND)」で一つにまWhenめるこWhenも可能です。

``````  if x_mar == 2 && z_mar >= 3
puts "True"
elsif y_mar == 2 && z_mar >= 3
puts "True"
else
puts "False"
end
``````
