Question

In data analysis, the eliminate agorithm determines the single final value to use for each data parameter. The criate algorithm works in the following way • Date is acquired from multiple sources in order from least to most preferred, Leif a parameter is present in both source Tand source Z the parameter from the higher priority source, source 2 is used in the final parameter list and any value from an earlier sources superseded . As new parameters arrive they are added to the list. . If a parameter Pik presentanty in one of the sources, it is directly added to the final parameter list Hence. .

Answer 1

The question asks for the implementation of an algorithm that selects parameter values from multiple sources based on their priority, ensuring the highest-priority value for each parameter is in the final list.

Step-by-step explanation:

The question pertains to a data analysis scenario in which multiple sources provide values for various parameters, and the goal is to determine the final parameter list using a priority-based approach. The eliminate algorithm is described, which takes inputs from multiple sources and ensures that for each parameter, the value from the highest-priority source is used. If a new parameter is found in a higher-priority source, it replaces the previous value. The objective is to write a function computeParameterValue that applies this algorithm to a list of sources and determines the final parameter list, maintaining the order of first encounter for each key.

For example, with the list of sources S5, S7, and S8, the computeParameterValue function should return the final parameter list by considering each source's priority and the order in which keys are found. In the provided code template, this function takes a two-dimensional array of sources as input, where each row corresponds to a source's data, and the sources are presented in the order of lowest to highest preference.

Answer 2

The Eliminate Algorithm in data analysis combines values from multiple sources, favoring higher priority sources. Imagine gathering data for a recipe.

You have the following information:

Source A: Low priority. Milk: 1 cup.

Source B: Medium priority. Milk: 2 cups.

Source C: High priority. Milk: 1.5 cups.

The Eliminate Algorithm would choose the value from Source C(1.5 cups) since it has the highest priority. If no value for a parameter exists in a higher-priority source, it's added from the next available source.

For instance, if the recipe requires sugar and only Source B provides it (100 grams), that value is added directly.

This algorithm ensures consistency and prioritizes accuracy by using the most reliable data available.
