从一月份到十二月的英文全称依次是：“January”,“February”,“March”,“April”,“May”,“June”,“July”,“August”,“September”,“October”,“November”,“December”
对应的缩写依次是：“Jan.”,“Feb.”,“Mar.”,“Apr.”,“May.”,“Jun.”,“Jul.”,“Aug.”,“Sep.”,“Oct.”,“Nov.”,“Dec.”。注意首字母大写，后面有个“.”
现在用户来输入一个月份的英文，请程序输出对应的英文缩写，无论用户的单词是大写还是小写，均应给出正确的英文缩写。如果输入的英文单词错误，请输出“Error”
例如，用户输入“JULY”，程序应输出“Jul.”
若用户输入的是“augest”，程序应输出“Error”
