an Office consisting of m cabins enumerated from 1 to m. Each cabin is 1 meter long. Sadly, some cabins are broken and need to be repaired.You have an infinitely long repair tape. You want to cut some pieces from the tape and use them to cover all of the broken cabins. To be precise, a piece of tape of integer length t placed at some positions will cover segments 5,5+1-sit-1.You are allowed to cover non-broken cabins, it is also possible that some pieces of tape will overlap.Time is money, so you want to cut at most k continuouspieces of tape to cover all the broken cabins. What is theminimum total length of these pieces?Input FormatThe first line contains three integers n,m and k(1sns10°, namsloº, Isksn) - the number of broken cabins, the length of the stick and the maximum number of pieces you can useThe second line contains n integers bl,b2,bn (Isbism) - the positions of the broken cabins. These integers are given in increasing order, that is, blOutput Format:Print the minimum total length of the piecesInput:Input:4 100 220 30 75 80Output17
