题目描述
给定n个字符串,请对n个字符串按照字典序排列。
输入描述:
输入第一行为一个正整数n(1≤n≤1000),下面n行为n个字符串(字符串长度≤100),字符串中只含有大小写字母。
输出描述:
数据输出n行,输出结果为按照字典序排列的字符串。app
解法1(C语言):ide
#include<stdio.h> #include<stdlib.h> #include<string.h> int Partition(char *A[], int low, int high) { char *pivot = (char *)malloc(100 * sizeof(char)); pivot = A[low]; while(low < high) { while(low < high && strcmp(A[high],pivot) >= 0) --high; A[low] = A[high]; while(low < high && strcmp(A[low],pivot) <= 0) ++low; A[high] = A[low]; } A[low] = pivot; return low; } void QuickSort(char *A[], int low, int high) { if(low < high) { int pivotpos = Partition(A, low, high); QuickSort(A, low, pivotpos - 1); QuickSort(A, pivotpos + 1, high); } } int main() { int n, i; char *str[1000]; scanf("%d", &n); for(i = 0; i < n; ++i) { str[i] = (char*) malloc(100*sizeof(char)); scanf("%s", str[i]); } QuickSort(str, 0, n - 1); for(i = 0; i < n; ++i) printf("%s\n", str[i]); return 0; }
解法2(Python):ui
n = int(input()) lst = [] for i in range(n): s = input() lst.append(s) lst.sort() for i in range(n): print(lst[i])
