Package for this problem was not updated by the problem writer or Codeforces administration after we’ve upgraded the judging servers. To adjust the time limit constraint, solution execution time will be multiplied by 2. For example, if your solution works for 400 ms on judging servers, then value 800 ms will be displayed and used to determine the verdict.

standard outputA two dimensional array is called a bracket array if each grid contains one of the two possible brackets — "(" or ")". A path through the two dimensional array cells is called monotonous if any two consecutive cells in the path are side-adjacent and each cell of the path is located below or to the right from the previous one.

A two dimensional array whose size equals *n* × *m* is called a correct bracket array, if any string formed by writing out the brackets on some monotonous way from cell (1, 1) to cell (*n*, *m*) forms a correct bracket sequence.

Let's define the operation of comparing two correct bracket arrays of equal size (*a* and *b*) like that. Let's consider a given two dimensional array of priorities (*c*) — a two dimensional array of same size, containing different integers from 1 to *nm*. Let's find such position (*i*, *j*) in the two dimensional array, that *a*_{i, j} ≠ *b*_{i, j}. If there are several such positions, let's choose the one where number *c*_{i, j} is minimum. If *a*_{i, j} = "(", then *a* < *b*, otherwise *a* > *b*. If the position (*i*, *j*) is not found, then the arrays are considered equal.

Your task is to find a *k*-th two dimensional correct bracket array. It is guaranteed that for the given sizes of *n* and *m* there will be no less than *k* two dimensional correct bracket arrays.

Input

The first line contains integers *n*, *m* and *k* — the sizes of the array and the number of the sought correct bracket array (1 ≤ *n*, *m* ≤ 100, 1 ≤ *k* ≤ 10^{18}). Then an array of priorities is given, *n* lines each containing *m* numbers, number *p*_{i, j} shows the priority of character *j* in line *i* (1 ≤ *p*_{i, j} ≤ *nm*, all *p*_{i, j} are different).

Please do not use the %lld specificator to read or write 64-bit integers in С++. It is preferred to use the cin, cout streams or the %I64d specificator.

Output

Print the *k*-th two dimensional correct bracket array.

Note

In the first sample exists only one correct two-dimensional bracket array.

In the second and in the third samples two arrays exist.

A bracket sequence is called regular if it is possible to obtain correct arithmetic expression by inserting characters «+» and «1» into this sequence. For example, sequences «(())()», «()» and «(()(()))» are regular, while «)(», «(()» and «(()))(» are not.
