我的代码:
class Solution {
public:
vector> combinationSum(vector& candidates, int target) {
sort(candidates.begin(),candidates.end());
vector> result;
vector one;
comb(candidates,target,0,one,result);
return result;
}
void comb(vector& can,int target,int index, vector& one,vector>& result){
if(target==0){
result.push_back(one);
return;
}
if(target<0){
return;
}
for(int i=index;i

动态规划代码:
class Solution {
public:
int uniquePaths(int m, int n) {
int dp[m][n];
for(int i=0;i
优化:
class Solution {
public:
int uniquePaths(int m, int n) {
if(m<=0||n<=0){
return 0;
}
int dp[n];
for(int i=0;i
在前一题的动态规划基础上加一些判断,但是存在一个整数溢出的问题,改成long,long long也没有用
1.暴力解法:
class Solution {
public:
int lengthOfLongestSubstring(string s) {
int length = 0;
for(int i=0;ilength){
length = news.length();
}
}
return length;
}
};
2.滑动窗口
class Solution {
public:
int lengthOfLongestSubstring(string s) {
string news = "";
int length = 0;
int left = -1;
for(int i=0;ileft?loc:left;
cout<length){
length = i-left;
}
}
return length;
}
};
3.评论中看到的一个
class Solution {
public:
int lengthOfLongestSubstring(string s) {
int size,i=0,j,k,max=0;
size = s.size();
for(j = 0;j max)
max = j-i+1;
}
return max;
}
};
