Trung is bored with his mathematics homeworks. He takes a piece of chalk and starts writing a sequence of consecutive integers starting with 1 to N (1 < N < 10000) . After that, he counts the number of times each digit (0 to 9) appears in the sequen…

UVa 1225 题目大意:把前n(n<=10000)个整数顺次写在一起,12345678910111213...,数一数0-9各出现多少字 解题思路:用一个cnt数组记录0-9这10个数字出现的次数,先将cnt初始化为0,接着让i从1枚举到n, 对每个i,处理以活的i的每一个位置上的数,并在相应的cnt下标上+1 最后输出cnt数组即可 /* UVa 1225 Digit Counting --- 水题 */ #include <cstdio> #include <cstring…

思路: 利用java 特性,将数字从1 一直加到n,全部放到String中,然后依次对strring扫描每一位,使其carr[str.charAt(i)-'0']++; 最后输出carr[i],即可. 13 string=12345678910111213 carr[1]++.carr[2]++.carr[3]++....carr[1]++.carr[1]++.carr[1]++.carr[2]++.carr[1]++.carr[3]++ AC Code: import java.util.Sc…
