most of the pionts are covered so far, I would like to add
one more point here,

In search all to get expected results array must be in a
specified order, but search all also works for an unsorted
array but may or may not give the expected results as it
keeps on divide.

Ex1: searching for 10. ** Array is not in order**

40
30
34
70
10
90

Iteration 1: it selects the second half 70,10,90
Iteration 2: It selects 10 n says the value is found.

Ex2: searching for te same 10.

40
10
34
70
30
90

Its follows the same process as in 1st case, but here 10 is
not there in the second iteration so it says value not
found, but it is present in the first half, this happens
because aray is not sorted.
