leastNum(numArray);
}
}
A.
100
B.
20
C.
6
D.
2
D. 2
Explanation:
The given code is a Java program that finds the least number in an array. The program defines a class called "minNumber" and within that class, there is a static method called "leastNum()" which takes an integer array as its parameter. Within the leastNum() method, a variable "least" is initialized with the value of the first element of the array. Then, the program uses a for loop to iterate through the array, starting at the second element. In each iteration of the loop, the program compares the value of the current element in the array to the value of the "least" variable. If the current element is less than the value of the "least" variable, the value of the "least" variable is updated to the value of the current element. After the loop is finished, the program prints the value of the "least" variable which is the least number in the array.
In the main method, an array of integers is created with values {100,20,6,2}. The leastNum() method is called and passed the numArray as an argument. As the least number in the array is 2, the output of the program will be 2.
given string workstr on one line and integer beginindex on a second line, assign finalstr with workstr the substring of workstr starting from the index beginindex to the end. ex: if the input is: fuzzy bear 4 then the output is: fuzzy beary bear note: recall string's length() returns the length of the string. ex: mystring.length().
A string is often regarded as a data type and is frequently implemented as an array data structure made up of bytes (or words) that uses character encoding to hold a sequence of components, typically characters.
What types of strings are examples?A string is any group of characters that a script interprets literally. Examples of strings include "hello world" and "LKJH019283."

Which of the following algorithms displays the correct distance for all possible values of num1 and num2?
The Euclidean distance technique provides the accurate distance for all conceivable values of num1 and num2. It is a measurement of the spherical distance in multidimensional space between two places.
For all feasible values of num1 and num2, the Euclidean Distance algorithm, also known as L2 distance, provides the accurate distance. By calculating the straight-line distance between the two points, this algorithm determines how far apart two points are in a multidimensional space. Euclidean distance is calculated using the formula: ((num1 - num2)2 + (num1 - num2)2 +... + (num1 - num2)2), where num1 and num2 are the coordinates of the two points being compared. For activities like clustering and classification, this technique is frequently employed in machine learning and data analysis. It is also commonly used in pattern recognition, computer vision, and image processing. The Euclidean Distance algorithm, as a whole, is a trustworthy and often applied technique for figuring out distance between points in a multidimensional space.

Give a contrapositive proof: For every undirected graph G (with no self-loops
or multi-edges) with n nodes, if G has more than 3(n−1) edges, then there exist 2 nodes
that both have degree at least 6.
A contrapositive proof states that if the negation of the conclusion is true, then the negation of the hypothesis is also true. In this case, the hypothesis is that G has more than 3(n−1) edges and the conclusion is that there exist 2 nodes that both have degree at least 6.
What would be the contrapositive proof?
So, the contrapositive proof would be:
If there does not exist 2 nodes that both have degree at least 6, then G has less than or equal to 3(n−1) edges.
Proof:
Let's assume that there does not exist 2 nodes that both have degree at least 6.
This means that the maximum degree of any node in G is less than 6.
Therefore, the sum of all degrees in G is less than 6n.
But we know that for any undirected graph, the sum of all degrees is equal to twice the number of edges, because each edge contributes 2 to the sum of degrees (one for each endpoint).
Therefore, the number of edges in G is less than 3n.
But since G has no self-loops or multi-edges, the number of edges is less than or equal to n(n-1)/2.
Therefore, 3n < n(n-1)/2
This implies n<3, which is not true, as n is the number of nodes in G.
Therefore, our assumption that there does not exist 2 nodes that both have degree at least 6 is not true.
So, we can conclude that G has less than or equal to 3(n−1) edges.

What happens when we use new and delete operator?The delete operator can be utilised to release dynamically allocated memory. Memory is released to the pool of memory that is currently available when the delete operator is used. If a class destructor is present, using the delete operator also calls it. A dynamic allocation of memory for an item or an array of objects on the heap is accomplished using the new operator.
Also used to deallocate memory is the delete operator. The two key operators in C++, new and delete, are the subject of this article. Examples from programmes are used to explain these operators. For deliberately managed lifetimes, the new and delete operators are built. The "object's" structure or size are decided upon during runtime, which is another typical explanation. simple instances (arrays, etc.)
