若自然数n使得作竖式加法n+(n+1)+(n+2)各位数均不产生进位现象，则成n为"可连数"，例如32是"可连数"，因32+33+34不产生进位现象；23不是"可连数"，因为23+24+25产生了进位现象，41也不是可连数，那么小于200的"可连数"的个数为多少．

If the natural number n makes the vertical addition n+(n+1)+(n+2) all the digits do not have a carry phenomenon, then n becomes a "continuous number", for example, 32 is a "continuous number", because 32+ 33+34 does not produce a carry phenomenon; 23 is not a "continuous number", because 23+24+25 produces a carry phenomenon, and 41 is not a continuous number, so how many "continuous numbers" are less than 200?
