12.2 -Querying a BST - Yep. All of it. 12.3 -Insertion/Deletion - Same as 12.2 12.4 -Randomly built BSTs - just know Theorem 12.4 (expected height of random BST is O(lgn)) and an idea of why it's true. Chapter 13 This one is easy. Know what a Red-Black tree is, and what i...
Deletion: swap the node that was intended to be deleted (usually the root for max or min element) with the leaf, delete the leaf, and max(min)heapify the heap, the run time is also O(nlogn). Build heap: assume all the data are stored in an array. We simply scan through all the...

In this algorithm deletion, insertion etc. operations are used to prioritize among nodes with different values. We combine these operations using a BST as a priority queue. This algorithm also uses the term probability of survival, which indicates the probability of a person surviving. A flexible...
MinDeletionUniqueFrequency Kotlin • questions Minimum Deletions to Make Character Frequencies Unique A string s is called good if there are no two different characters in s that have the same frequency. Given a string s, return the minimum number of characters you need to delete to make s...

The 32 bp deletion in CCR5 may be associated with breast cancer, and the malformed CCR5 receptor may not be able to express and function normally, thereby reducing immunity to cancer and leading to cancer progression [45]. Gene Set Enrichment Analysis (GSEA) revealed the association of ...
for (int i = 1; i < in.length(); i++) { if (in.charAt(i) == last) { c++; continue; } else { next.append((char)(c+'0')); next.append(last); last = in.charAt(i); c = 1; } } //last char next.append((char)(c+'0')); next.append(last); in = next; count++...
如果忘记了BST的性质,先去上面复习一下 Insertion 和 Deletion 的操作。13.1. RotationWhen we do a left rotation on a node x, we assume that its right child y is not T:nil; x may be any node in the tree whose right child is not T:nil. The left rotation “pivots” around the link ...
Capture exceptions by by reference (to avoid the problem of object deletion and cutting of exception objects, retain the ability to catch standard exceptions, and restrict the number of times an exception object needs to be copied) Use exception specifications wisely (exception specifications provide ...
