【问题描述】：

如何将这些 while 循环表述为 for 循环？我认为 for 循环更好看，并希望摆脱这些 while 循环。我怎么做？我不知道。

number_of_vertices = number_of_nodes - 1

nodes_array = np.zeros(number_of_nodes)

starting_number = 7
nodes_array[starting_number - 1] = 1

def find_min():
    min_dist = 10000
    from = -1
    to = -1
    
    i = 0
    while i < len(nodes_array):
        if nodes_array[i] == 1:
            j = 0
            while j < len(nodes_array):
                if min_dist > dist[(i, j)] and dist[(i, j)] != 0 and nodes_array[j] != 1:
                    min_dist = dist[(i, j)]
                    from = i
                    to = j
                j = j+1
        i = i+1
    print("(" + str(from+1) + "," + str(to+1) +"): Distance"+ str(min_dist))
    nodes_array[to] = 1

x = 0
while x < number_of_nodes-1:
    find_min()
    x += 1```

• java: for i = 0; i
