Description
- If the tens digit of a number is 1, then write "th" after the number. For example: 13th, 19th, 112th, 9311th.
- If the tens digit is not equal to 1, then use "st" if the units digit is 1, "nd" if the units digit is 2, "rd" if the units digit is 3, and "th" otherwise: For example: 2nd, 7th, 20th, 23rd, 52nd, 135th, 301st.
Input
There are multiple test cases. The first line of input is an integer T ≈ 1000 indicating the number of test cases.
Each test case consists of a cardinal number 0 ≤ n < 1,000,000,000.
Output
For each test case, output the corresponding ordinal number.
Sample Input
5 1 2 3 4 1024
Sample Output
1st 2nd 3rd 4th 1024th
分析:
题意就是让输出对应的英文缩写。。。
上原码:
#include<stdio.h> int main() { int t, n, m; scanf("%d", &t); while(t--) { scanf("%d", &n); if((n / 10) % 10 == 1) printf("%dth\n", n); else { m = n % 10; printf("%d", n); if(m == 1) puts("st"); else if(m == 2) puts("nd"); else if(m == 3) puts("rd"); else puts("th"); } } return 0; }
