The principal idea is to construct solutions single component at a time and evaluate such partially constructed candidates as follows.
If a partially constructed solution can be developed further without violating the problem's constraints, it is completed by taking the first remaining legitimate option for the next component.
If there is no legitimate option for the next component, no alternatives for any remaining component require to be considered.
Q. Write down the algorithm which does depth first search through an un-weighted connected graph. In an un-weighted graph, would breadth first search or depth first search or neith
Q. What do you mean by the best case complexity of quick sort and outline why it is so. How would its worst case behaviour arise?
A B-tree of minimum degree t can maximum pointers in a node T pointers in a node.
how to define the size of array
Best Case: If the list is sorted already then A[i] T (n) = c1n + c2 (n -1) + c3(n -1) + c4 (n -1) = O (n), which indicates that the time complexity is linear. Worst Case:
one to many one to one many to many many to one
Stacks are often used in evaluation of arithmetic expressions. An arithmetic expression contains operands & operators. Polish notations are evaluated through stacks. Conversions of
The searching method are applicable to a number of places in current's world, may it be Internet, search engines, text pattern matching, on line enquiry, finding a record from data
