# Minimum Number of Calls to be made ?

 0 There are 'n' number of detectives..each one knows an information, how many minimum calls should they make so all the detectives know all the n number of information ? My answer: I came up with 2n-3 (that is, n-1 + n-2) solution where a detective calls n-1 other detectives and shares information mutually (in this way the last detective and the first has all the information). Then the remaining n-2 detectives who doesn't have the whole data calls either the first detective or the last to gain the remaining information. asked 28 Sep '13, 23:31 6●2●2●4 accept rate: 0%

 3 @saikiranboga11 : Hello , sorry my earlier comment was wrong so I have deleted it. The paper you mentioned is about a must broader result and hence is difficult to follow . If you are just interested in the base problem , have a look at this paper http://www.mathematik.uni-bielefeld.de/~sillke/PUZZLES/gossips.pdf It has a one page solution and is easily followable Hope that helps . answered 29 Sep '13, 07:20 12.4k●47●107●171 accept rate: 12%
