PTA tiantisai l1-079 tiantisai's kindness (20 points) detailed explanation

The ladder race is a kind race . The kind proposition group hopes to control the difficulty of the topic within a range , So that each participating student has a topic that can be done , And the best students have to work very hard to get high marks .

So the proposition group first divides the programming ability into 106 Level （ It's crazy , It's a fake ）, Then we investigated the programming ability of each participating student. . Now please write a program to find out the minimum and maximum abilities of all participating students , Give the proposition group as a reference .

Input format ：

Input gives a positive integer in the first line N（≤2×104）, That is, the total number of students participating . The next line shows N No more than one. 106 The positive integer , Is the ability value of the participating students .

Output format ：

The first line outputs the minimum ability value of all participating students , And the number of students with this ability value . The second line outputs the maximum ability value of all participating students , And the number of students with this ability value . Peer numbers are separated by 1 Space separation , There must be no extra space at the beginning and end of the line .

sample input ：

10
86 75 233 888 666 75 886 888 75 666

sample output ：

75 3
888 2

Detailed code ：

#include <stdio.h>
int main()
{
	int n, a[20000], max = 0, min = 2000000, mi = 0, ma = 0;
	scanf("%d", &n);
	for (int i = 0; i < n; i++)
		scanf("%d", &a[i]);
	for (int i = 0; i < n; i++)
	{
		if (a[i] > max)
			max = a[i];
		if (a[i] < min)
			min = a[i];
	}
	for (int i = 0; i < n; i++)
	{
		if (a[i] == max)
			ma++;
		if (a[i] == min)
			mi++;
	}
	printf("%d %d\n", min, mi);
	printf("%d %d\n", max, ma);
