Best Partition
You are given an array of positive numbers of size N and an integer K. You need to partition the array into K
continuous segments. For each segment, the sum of its elements needs to be calculated.
The segment with the minimum sum is called the bestSegment and the sum of the elements of the
bestSegment is called the bestSum.
For all possible combinations of partitions of the array when divided into K segments, their bestSum needs to be
calculated and the one among them with maximum value needs to be returned.
Input Specification:
input1: an array of N positive numbers
input2: an integer N denoting the length of the array
input3: an integer K
Output Specification:
Return an integer denoting the maximum value of all possible bestSum.
Example 1:
input1: (1,2,3,4}
input2: 4
input3: 2
Output: 4
Explanation:
You can partition the given array into 2 continuous segments in the following manner-
• 123 14- the sum of individual segments is (6,4) and the bestSum is 4
• 12134- the…
Interpolation search By using interpolation search algorithm check if the given element exists in the integer one dimensional array return the index of it ( data structure in java)
AIM: Write a program to do Linear Search using a given Search Key in an un-
sorted Linear Array 'A' which has N values in it.
Description:
The linear search compares each element of the array with the search key until the
search key is found. To determine that a value is not in the array, the program must
compare the search key to every element in the array 'A'. It is also called "Sequential
Search" because it traverses the data sequentially to locate the element.
Algorithm: (Linear Search)
LINEAR
SEARCH (A, N, SKEY)
Here A is a Linear Array with N elements and SKEY is a given item
of information to search. This algorithm finds the location of SKEY in
A and if successful, it returns its location otherwise it returns -1 for
unsuccessful.
1.
Repeat step-2 for K = 0 to N-1
2. if(A [K] = SKEY) return K [Successful Search]
[End of loop of step-1 ]
3. return -1 [Un-Successful]
4. End.

For example when given = [1,3,5,6,10] a b = [1,4,6,8] %3D the resulting array should be: C = = [1,1,3,4,5,6,6,8,10] This method should not call a sorting method. Instead, the resulting array should be produced by "zipping" the two input arrays together: we repeatedly select the least element that we did not consider before from a and b and include this in c. For example: a = [1,3,5,6,10] b = [1,4,6,8] C = [1,1,3, ...] the arrows (^) point to the lowest element we did not consider before. Of these, element 4 from b is less than element 5 from a. For this reason, we select 4 as the next element and advance the arrow ^ for b to point to 6.arrow_forward
