Answer_____

Conside the integers from 1 to 10,000,000.Calculate the number of integers that have the digit 1 in their representation.Answer_____
在所有1-10,000,000的整数中,有几个数位中包含“1”的
将不足7位的数视作前面有0.
故此,从0,000,001到9,999,999中,所有“没有1”的数共有9^7=4782969个
那么有一的就有9,999,999-4,782,969+1=5,217,031个

这明明是英语么。。你翻译出来。。啦

Conside整数1至10,000,000 。计算人数,整数有1位在其代表性

看不懂英文

找出其中有1的数的总数 可以尝试用排列组合试试

假设在从1到10 000 000 的整数中,计算含有数字“1”的整数个数。
计算就不会啦~~

排列组合问题 除去10 000 000外就有9 999 999个数 看作7个格子 把023456789填进去就保证不含1 所以有9的7次方个 所以9 999 999减去9的7次方在把10 000 000这个数加进来 答案就是10的7次方 减 9的7次方
