Implementation hiding i<u>s the encapsulation of method details within a class</u>. Implementation can be interpreted as those specifications which can be altered without altering the correctness of an application. Wrapping data/methods within classes (descriptions of the way all objects of this type will look/act) in combination with implementation hiding is called encapsulation. Information users need to know about behaviors should be available without dependence on implementation specifications.
Answer:
True: In binary search algorithm, we follow the below steps sequentially:
Input: A sorted array B[1,2,...n] of n items and one item x to be searched.
Output: The index of x in B if exists in B, 0 otherwise.
- low=1
- high=n
- while( low < high )
- { mid=low + (high-low)/2
- if( B[mid]==x)
- {
- return(mid) //returns mid as the index of x
- }
- else
- {
- if( B[mid] < x) //takes only right half of the array
- {
- low=mid+1
- }
- else // takes only the left half of the array
- {
- high=mid-1
- }
- }
- }
- return( 0 )
Explanation:
For each iteration the line number 11 or line number 15 will be executed.
Both lines, cut the array size to half of it and takes as the input for next iteration.
Answer:
1. =CONCATENATE(" John"," ","Smith")
2. =(" John"&" "&"Smith")
Explanation:
Given
Two separate strings; "John" and "Smith"
Required
2 separate formulas to concatenate both strings to form " John Smith"
There are several ways to concatenate strings in Microsoft Office Excel; one of the methods is using the concatenate function while the another method is using the traditional & operator.
Using the concatenate function, the formula is as follows
=CONCATENATE(" John"," ","Smith")
This function will combine the " John", " " and "Smith" to give a new string " John Smith" (without the quotes).
Using the traditional & operator may be a little bit difficult (and not frequently used) but the formula is as follows;
=(" John"&" "&"Smith")
The result will be the same as (1) above
