Problem:


チーズ (Cheese)

問題

今年も JOI 町のチーズ工場がチーズの生産を始め，ねずみが巣から顔を出した．JOI 町は東西南北に区画整理されていて，各区画は巣，チーズ工場，障害物，空き地のいずれかである．ねずみは巣から出発して全てのチーズ工場を訪れチーズを 1 個ずつ食べる．

この町には，N 個のチーズ工場があり，どの工場も１種類のチーズだけを生産している．チーズの硬さは工場によって異なっており，硬さ 1 から N までのチーズを生産するチーズ工場がちょうど 1 つずつある．

ねずみの最初の体力は 1 であり，チーズを 1 個食べるごとに体力が 1 増える．ただし，ねずみは自分の体力よりも硬いチーズを食べることはできない．

ねずみは，東西南北に隣り合う区画に 1 分で移動することができるが，障害物の区画には入ることができない．チーズ工場をチーズを食べずに通り過ぎることもできる．すべてのチーズを食べ終えるまでにかかる最短時間を求めるプログラムを書け．ただし，ねずみがチーズを食べるのにかかる時間は無視できる． 

入力

入力は H+1 行ある．1 行目には 3 つの整数 H，W，N (1 ≤ H ≤ 1000，1 ≤ W ≤ 1000，1 ≤ N ≤ 9) がこの順に空白で区切られて書かれている．2 行目から H+1 行目までの各行には，'S'，'1', '2', ..., '9'，'X'，'.' からなる W 文字の文字列が書かれており，各々が各区画の状態を表している．北から i 番目，西から j 番目の区画を (i,j) と記述することにすると (1 ≤ i ≤ H, 1 ≤ j ≤ W)，第 i+1 行目の j 番目の文字は，区画 (i,j) が巣である場合は 'S' となり，障害物である場合は 'X' となり，空き地である場合は '.' となり，硬さ 1, 2, ..., 9 のチーズを生産する工場である場合はそれぞれ '1', '2', ..., '9' となる．入力には巣と硬さ 1, 2, ..., N のチーズを生産する工場がそれぞれ 1 つずつある．他のマスは障害物または空き地であることが保証されている．ねずみは全てのチーズを食べられることが保証されている．

すべてのチーズを食べ終えるまでにかかる最短時間（分）を表す整数を 1 行で出力せよ．
