# 思路：模拟
a = input()
a += "*"#添加个字符，以免15行那里越界
b = ""
i = 0
while True:
    if i == len(a):  # 找完了
        break
    if not a[i].isdigit():  # 开头不为数字
        b += a[i]
        i += 1
        continue
    else:  # 开头为数字
        for j in range(i, len(a)):
            if a[i:j].isdigit() and not a[i : j + 1].isdigit():
                b += "*" + a[i:j] + "*"
                i = j
                break
print(b[: len(b) - 1])#最后输出记得删掉添加的字符
