We have a grid with H rows and W columns, where all the squares are initially white.  You will perform some number of painting operations on the grid. In one operation, you can do one of the following two actions:    * Choose one row, then paint all the squares in that row black.   * Choose one column, then paint all the squares in that column black.  At least how many operations do you need in order to have N or more black squares in the grid? It is guaranteed that, under the conditions in Constraints, having N or more black squares is always possible by performing some number of operations.
H = 14
W = 12
N = 112

if H <= W:
    if N % W == 0:
        print(int(N/W))
    else:
        print(int(N//W) + 1)
else:
    if N % H == 0:
        print(int(N/H))
    else:
        print(int((N//H) + 1))
H = int(input())
W = int(input())
N = int(input())

if H <= W:
    if N % W == 0:
        print(int(N/W))
    else:
        print(int((N//W) + 1))
else:
    if N % H == 0:
        print(int(N/H))
    else:
        print(int((N//H) + 1))
