When multiple audio files are suggested in the audio element, the browser will play the first supported audio file format that it can handle.

The audio element in HTML allows developers to provide multiple source files for the browser to choose from. These source files are specified using the `<source>` element within the audio element. Each `<source>` element can have a different audio file format and optionally specify additional attributes like codecs and MIME types. The browser will evaluate the list of provided source files in the order they appear in the HTML markup. It will attempt to play the first source file that it supports based on its capabilities and the formats specified. If the browser can't play the first file, it will move on to the next source file in the list and continue until it finds a supported format or exhausts all the provided options. Therefore, the first supported audio file format in the list of suggested sources is the one that will be played by the browser.

If all n2 elements of a2 appear in the n1 element array a1 in the same order, then a2 is a subsequence of a1.

If all n2 elements of a2 appear in the n1 element array a1 in the same order, then it can be said that a2 is a subsequence of a1. This means that a2 is a part of a1 and can be obtained by deleting some of the elements from a1. It is important to note that the order of the elements in a2 must be preserved in a1, but they do not need to be consecutive.

In order to determine if a2 is a subsequence of a1, one can use a simple algorithm that checks if each element in a2 appears in a1, starting from the first element of a2. If an element is found, the algorithm moves to the next element in a2 and continues the search in a1 starting from the index of the previously found element. If all elements in a2 are found in a1 in the same order, then a2 is a subsequence of a1.

In conclusion, if all n2 elements of a2 appear in the n1 element array a1 in the same order, then a2 is a subsequence of a1. This can be determined using a simple algorithm that checks if each element in a2 appears in a1 in the correct order.

The asymptotic running time of the recursive Weighted Interval Scheduling (WIS) algorithm depends on its specific implementation. However, in general, the recursive WIS algorithm has a running time of O(n^2), where n represents the number of vertices or intervals.

The recursive WIS algorithm solves the Weighted Interval Scheduling problem by recursively considering all possible choices and selecting the one with the maximum weight. In each recursive step, the algorithm explores all remaining intervals to make a decision. Since there can be up to n intervals at each step, and this process is repeated for each interval, the overall running time is O(n^2). Note that this analysis assumes that the algorithm does not employ any memoization or dynamic programming techniques to avoid redundant computations. If such techniques are utilized, the running time can be significantly improved.

The statement that the binary recursion solution is always faster than linear recursion is false.

The efficiency of a recursive algorithm depends on various factors, including the problem itself, the specific implementation, and the input data.

In some cases, binary recursion may provide a more efficient solution compared to linear recursion. For example, when performing operations on sorted data or when dividing the problem into halves, binary recursion can lead to faster convergence or reduce the number of recursive calls.

However, it is not a general rule that binary recursion is always faster. Linear recursion can also be efficient for certain problems or input scenarios. It may have a simpler implementation or require fewer recursive calls, resulting in comparable or better performance compared to binary recursion.

To determine the most efficient approach, it is important to consider the specific problem, analyze the algorithm's time and space complexity, and conduct performance testing and benchmarking with representative data. Optimizing recursive algorithms often involves finding the most appropriate approach based on the problem's characteristics and requirements rather than assuming one type of recursion will always be faster than the other.

Under protected inheritance, the properties and methods of the parent class will have a protected visibility in the child class. This means that the child class can access and use these properties and methods within its own code, but they will not be visible or accessible outside of the class or any of its derived classes. Protected inheritance is a type of inheritance in which the public and protected members of the parent class become protected members of the child class, while the private members remain inaccessible.

In protected inheritance, the public and protected members of the base class become protected members in the derived class. This means that the child class can access the protected members of the base class directly, but they are not accessible outside the class or in derived classes further down the inheritance hierarchy. The public members of the base class, on the other hand, remain protected in the derived class.

TRUE. The costs of technology are often high for developers and early adopters, but they tend to decrease gradually over time. This is due to several factors, including increased competition, economies of scale, and improvements in manufacturing processes.

When a new technology is first introduced, it is often expensive to produce because there is a limited market for it and the cost of development and research needs to be recouped. Developers and early adopters are usually willing to pay a premium for the latest and greatest technology, which also contributes to the high costs. However, as the technology becomes more widespread, economies of scale come into play. Manufacturing processes become more efficient, and the cost of production decreases. In addition, as more competitors enter the market, prices are driven down further.

As a result, the cost of technology usually decreases over time, making it more accessible to a broader range of consumers. This is often seen with consumer electronics, such as smartphones and laptops, where the latest models are initially expensive but become more affordable as newer models are released.
