C++解答

#include <stdio.h>
#include <iostream>

using namespace std; 

int  main(){
	int i, j, c = 0, d =0, n, a[100], b[100];
	std::cin>>n;
	for(i = 0; i <n; i ++)
		cin>>a[i];
	for(i = 0; i <n; i ++)
		for(j = i+1; j < n; j ++)
		{
			d = a[i]-a[j];
			if(d < 0)
				b[c]= -d;
			else b[c] = d;
			c++;
			
		}
	for(i = 1; i < (n*n-n)/2; i ++)
	{	
		if(b[0]>b[i])			
		b[0]=b[i];
	}
	cout<<b[0]<<endl;
	return 0;
}

Python解答

#!python
# -*- coding: utf-8 -*-  

#输入
n = int(raw_input())
q = raw_input().split(' ')
q = [int(i) for i in q]

#差值列
x = []
minx = abs(q[0] - q[1])

for i in range(n-1):
	qp = q[i+1:]
	x = [q[i] - s for s in qp]
	absx = map(abs, x)
	minx = minx if minx < min(absx) else min(absx)

print minx
