The Dancing Links algorithm solving a polycube puzzle. In computer science, dancing links (DLX) is a technique for adding and deleting a node from a circular doubly linked list. It is particularly useful for efficiently implementing backtracking algorithms, such as Knuth's Algorithm X for the exact cover problem. [1]
Linked list implementations, especially one of a circular, doubly-linked list, can be simplified remarkably using a sentinel node to demarcate the beginning and end of the list. The list starts out with a single node, the sentinel node which has the next and previous pointers point to itself. This condition determines if the list is empty.
The Central Board of Secondary Education (CBSE) is a national-level board of education in India for public and private schools, controlled and managed by the Government of India. Established in 1929 by a resolution of the government, the Board was an experiment towards inter-state integration and cooperation in the sphere of secondary education.
The results of the examinations are usually declared in the first week of May to mid-June. In general, about 80% of candidates receive a passing score. [8] The Delhi High Court has directed the Central Board of Secondary Education and Delhi University to discuss the ways by which the results of the main exam, revaluation, and compartment exam can be declared earlier than usual so that ...
The first and last nodes of a doubly linked list for all practical applications are immediately accessible (i.e., accessible without traversal, and usually called head and tail) and therefore allow traversal of the list from the beginning or end of the list, respectively: e.g., traversing the list from beginning to end, or from end to beginning, in a search of the list for a node with specific ...
A linked list is a sequence of nodes that contain two fields: data (an integer value here as an example) and a link to the next node. The last node is linked to a terminator used to signify the end of the list. In computer science, a linked list is a
The Council of CBSE Affiliated Schools in the Gulf (Arabic: مجلس مدارس سي بي إس إي في الخليج), or CBSE Gulf Sahodaya (English: CBSE Gulf Sahodaya) is a body of 193 principals of Central Board of Secondary Education-affiliated schools [2] [3] in the member states of the Gulf Cooperation Council, namely Bahrain, Kuwait, Oman, Qatar, Saudi Arabia, and the United Arab ...
Saransh is a web portal launched by Central Board of Secondary Education (CBSE) of India, with the primary aim of promoting information and communication technologies in schools. [1] The Human Resource Development Minister Smriti Irani launched the portal on 7 November 2015. [2] Saransh is a self-review tool for all CBSE affiliated schools and ...
