自己整理的八种排序(c/c++)-创新互联

//1.直接插入排序
void InsertSort(int A[],int n){
    int i,j;
    for(i = 2;i< n;i++){
        if(A[i-1] >A[i]){
        A[0] = A[i];
        for(j = i-1; jA[j] >A[0];--){
            A[j+1] = A[j];
        }
        A[j+1] = A[0];
        }
    }
}
1.1折半插入排序
void InsertSort(int A[],int n){
    int i,j,left,right,mid;
    for(i = 2;i< n; i++){
        A[0] = A[i];
        left = 1,right = i - 1;
         while(left<= right){
             mid = (left + right)/2;
             if(A[mid] >A[0])    right = mid - 1;
             else                 left = mid + 1; 
         }
         for(j = i - 1;j >= right + 1;j--){
             A[j + 1] = A[j];
         }
         A[j + 1] = A[0];
    }
}
2.冒泡排序
void BubbleSort(int A[],int n){
    int i,j;
    for(i = 0;i< n - 1; i++){
        bool flag = false;
        for(j = n - 1;j >i; j--){
            if(A[j - 1] >A[j]){
                swap(A[j - 1],A[j]);
                flag = true;
            }
        }
3.快速排序
int MAXN = 1000;
int arr[MAXN];

void Partition(int left,int right){
    while(left< right){
        while(left< right && arr[left]< arr[right]){
            right --;
        }
        swap(arr[left],arr[right]);

        while(left< right && arr[left]< arr[right]){
        left++;
        }
        swap(arr[left],arr[right]);
    }
    return left;
}


void QuickSort(int left,int right){
    if(left< right){
        int pos = Partition(left,right);
        QuickSort(left, pos - 1);
        QuickSort(pos + 1, right);
    } 
}
4.简单选择排序
void SelectSort(int A[],int n){
    int i,j,min;
    for(i = 0; i< n - 1; i++){
        min = i;
        for(j = i + 1;j< n; j++){
            if(A[min] >A[j]){
                min = j;
            }
            if(min != i)
            swap(A[min],A[i]);
        }
    }
}
        if(flag == false)  return;
    }
}
//5.归并排序
int arr[MAXN];
int temp[MAXN];

void Combine(int left,int mid,int right){
    int i = left;
    int k = left;
    int j = mid + 1;
    while(i<= mid && j<= right){
        if(arr[i]< arr[j])
        temp[k++] = arr[i++];
        else 
        temp[k++] = arr[j++];
    }    

    while(i<= mid)      temp[k++] = arr[i++];
    while(j<= right)    temp[k++] = arr[j++];

    for(k = left; k<= right; k++){
        arr[k] = temp[k];
    }
}


void MergeSort(int left,int right){
    if(left< right){
        int mid = (left + right)/2;
        MergeSort(left,mid);
        MergeSort(mid + 1,right);
        Combine(left,mid,right);
    }
}
