Stripies 28 апр 2002 03:15 The sample input for Stripies (# 1161) would be right if it were 4 72 30 50 30 giving same output 120 Is that right? Spatarel Dan Constantin Re: problem with input // Задача 1161. Stripies 2 апр 2006 14:52 Yes, that's right, but the sample input in also correct. ;) Chadnov Roman Is this prog not correct? [2] // Задача 1161. Stripies 11 мар 2002 14:42 var a:array[1..100] of longint; n,i,j:longint; max:extended; begin readln(n); max:=0; for i:=1 to n do begin readln(a[i]); for j:=1 to i-1 do if sqrt(a[j]*a[i])>max then max:=sqrt(a[j]*a[i]) end; writeln((max*2):0:2); end. Avanesov Re: Is this prog not correct? // Задача 1161. Stripies 20 мар 2002 20:34 No. Your program finds the maximal value of a[i]*a[j]. Your task is different. Let you have n numbers: a[1],...,a[n]. You can change any two numbers a[i], a[j] with 2*sqrt(a[i],a[j]). So you've got another sequence : b [1],...,b[n-1], where b[1]=a[1]; ... b[i-1]=a[i-1]; b[i]=2*sqrt(a[i],a[j]); b[i+1]=a[i+1]; ... b[j-1]=a[j-1]; b[j]=a[j+1]; ... b[n-1]=a[n]. Repeat procedure until you'll get the only integer. You are to find the minimal value of this number. Good luck! Votjakov Roman[Barnaul] Re: Is this prog not correct? // Задача 1161. Stripies 2 дек 2005 11:41 Its solution is not correct!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! Foo Chuan Sheng Problem with output files/problem description! [1] // Задача 1161. Stripies 8 дек 2001 22:02 My program gets wrong answer when only 2 digits after the decimal place are printed, but accepted when 3 digits after the decimal place are printed. I suspect the person who submitted this problem did not change the output files from the contest - those output files contain 3 digits after the decimal place! Admins please check. Thanks. Pavel Atnashev Re: Problem with output files/problem description! // Задача 1161. Stripies 9 дек 2001 12:00 Yes, there was a problem with testing program. Fixed. Thank you for your feedback.
