在数组的首尾各加入INT_MIN ,然后遍历数组。
3、代码
int findPeakElement(vector<int>& nums) {
if( nums.size() == )
return ; nums.insert( nums.begin(), INT_MIN );
nums.push_back( INT_MIN ); for( vector<int>::iterator it = nums.begin()+; it != nums.end() - ; ++it ){
if( *it > *(it + ) && *it > *(it-) )
return (it - nums.begin() - );
}
}
