【LintCode】1613. 最高频率的IP

1613. 最高频率的IP

给定一个字符串数组lines, 每一个元素代表一个IP地址，找到出现频率最高的IP。

样例

样例1:

输入 = ["192.168.1.1","192.118.2.1","192.168.1.1"]
输出  "192.168.1.1"

样例2:

输入 = ["192.168.1.1","192.118.2.1","192.168.1.1","192.118.2.1","192.118.2.1"]
输出 "192.118.2.1"

注意事项

给定数据只有一个频率最高的IP

public class Solution {
    /**
     * @param ipLines: ip  address
     * @return: return highestFrequency ip address
     */
    public String highestFrequency(String[] ipLines) {
        // Write your code here
        int a[] = new int[ipLines.length];
        for(int i =0;i=a[y]){
                    ip = ipLines[x];
                    ipLines[x] = ipLines[y];
                    ipLines[y] = ip;
                    
                    temp = a[x];
                    a[x] = a[y];
                    a[y] = temp;
                }
                
            }
            
        }
