题目描述:
Given an array of size n, find the majority element. The majority element is the element that appears more than ⌊ n/2 ⌋
times.
You may assume that the array is non-empty and the majority element always exist in the array.
代码:
class Solution {
public:
int majorityElement(vector<int> &num) {
public:
int majorityElement(vector<int> &num) {
int elem = 0;
int count = 0;
for(int i = 0; i < num.size(); i++) {
if(count == 0) {
elem = num[i];
count = 1;
}
else {
if(elem == num[i])
count++;
else
count--;
}
}
return elem;
}
int count = 0;
for(int i = 0; i < num.size(); i++) {
if(count == 0) {
elem = num[i];
count = 1;
}
else {
if(elem == num[i])
count++;
else
count--;
}
}
return elem;
}
};
