标 题: The time complexity on finding the kth largest element in a
发信站: BBS 未名空间站 (Tue Jun 1 22:42:09 2010, 美东)
We can use the partition() in qsort. Each time, we can partition the array
into two parts, array_a and array_b. Let the number of elements in array_a
and array_b be sa and sb, respectively.
If sa is smaller than k, then find the (k-sa)th largest element in array_b;
If sa is larger than or equal to k, then find |

我觉得是O(nlogn)
bool contain(node* root, node* cur)
{
if(root)
{
if(root==cur) return true;
return contain(root->left,cur)||contain(root->right,cur);
}
return false;
}
node* lowest(node* root, node* n1, node* n2)
{
if(root==n1||root==n2) return root;
if(root==NULL) return NULL;
bool isLeft1 = false;
bool isLeft2 = false;
if(root->left)
{
isLeft1 = contain(root->left,n1); ... 阅读全帖 |

Recurrence Algorithm Big-O Solution
T(n) = T(n/2) + O(1) Binary Search O(log n)
T(n) = T(n-1) + O(1) Sequential Search O(n)
T(n) = 2 T(n/2) + O(1) tree traversal O(n)
T(n) = T(n-1) + O(n) Selection Sort (other n2 sorts) O(n^2)
T(n) = 2 T(n/2) + O(n) Mergesort (average case Quicksort) O(nlog n) |

f(x) = f(x-1) + g(x)
g(x) = f(x-1) + g(x/2)
边界条件大概就是f(1) = a, g(0) = b什么的，不过也不重要.
最后要求f（x）的time complexity。

发帖数: 22 | 10 last character will be accessed n times; last second character will be
accessed n-1 times. the complexity is n+(n-1)+(n-2)+...1=O(n^2)
since you isPalindrome takes O(n), total will be O(n^3).
if you calculate isPlaindrome first, it takes O(n^2); in your recursive
function, it will take O(1) to call that function. overall complexiy will be
O(n^2). |
