Posted by Administrator

โจทย์การบ้าน นักเรียน ม.3

-------------
โรงแรมในฝัน (Hotel)
โรงแรมแคนทารีฮิลล์เป็นโรงแรมขนาดใหญ่ซึ่งมีจํานวนห้องพักไม่จํากัด โดย มีรายละเอียดประเภทห้องพัก
และราคาที่พักดังตารางต่อไปนี้


 
ประเภทของห้อง 	จํานวนคนที่พักมากที่สุดต่อห้อง		ราคาต่อห้อง(บาท)
ห้องเดี่ยว 		     1 				                  500
ห้องคู่ 			      2	                      800
ห้องกลาง 		    5                       1,500
ห้องพักรวม 		   15                      3,000

งานของคุณ
ให้เขียนโปรแกรมในการคํานวณหาห้องพักให้กับคนที่ต้องการเข้าพักจํานวน n คน โดยให้มีราคารวมของห้องพักต่ําที่สุด

ข้อมูลนําเข้า
มีหนึ่งบรรทัด เป็นจํานวนเต็มบวกที่เป็นค่าของ n โดยที่1 ≤ n ≤ 1,000,000

ข้อมูลส่งออก
มีหนึ่งบรรทัด เป็นจํานวนเต็มบวกที่เป็นราคารวมของห็องพักต่ำที่สุด

ตัวอย่างที่ 1
ข้อมูลนําเข้า
21
ข้อมูลส่งออก
5000

ตัวอย่างที่ 2
ข้อมูลนําเข้า
24
ข้อมูลส่งออก
6000าเข้า
