Link List

Link List Its usage provide faster program than usage of array. We use link list instead of array especially when we want to avoid the condition where array will be filled inside stack. Link list facilitate us to move further or backward. In doubly link list we have facility to move next and previous. In […]

Characteristics of Arrays With array we can run push and pop fastest by deciding where to inert and where to delete an element in array. We can use add(), remove() functions to add an element to array inside the list and remove respectively from the current position. Add() moves the elements to right and place […]

If “r” between two variables is zero, it doesn’t mean that there is no relationship between the variables.   Justification:   Condition-1-If “r” is near +1, it represents positive correlation b/w two variables. If one will increase other will increase too and vice versa.   Condition-2-If “r” is near -1, it represents negative correlation b/w […]

Websites are very quick source of information. Search engines put magic in this too. Although by experience we can observe information authenticity as well but CRAAP test help us in this regard a lot. CRAAP means   1-     Currency – Time to time information updated or not. 2-     Relevance – Information provided is relevant to […]
