报告可以替换为 case 语句的 if 语句。

使用最小分支数字段为得到的 case 语句指定最小 when 分支数。

示例:

fruit = gets

if fruit == 'apple' # Simplifiable 'if' statement
  puts 'This is apple!'
elsif fruit == 'peach'
  puts 'This is peach!'
elsif fruit == 'orange'
  puts 'This is orange!'
elsif fruit == 'banana'
  puts 'This is banana!'
end
