将整数 i 分解为字符串,然后遍历之,自增 k 出现的次数即可。 Java classSolution {/** param k : As description. * param n : As description. * return: An integer denote the count of digit k in 1..n*/publicintdigitCounts(intk,intn) {intcount = 0;charkChar = (char)(k + '0');fo...
Source Count the number of k's between 0 and n. k can be 0 - 9. Example if n=12, k=1 in [0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12], we have FIVE 1's ( ... git 字符串 自增 时间复杂度 java 转载
