There are 500 students the score range is 0 to 100. Print the frequency of those student whose score above 50. So frequency range contains score from 50 to 100, so an array of 50 numbers is suitable for representing the frequency.

Best way to store the frequencies
To determine the best way to store the frequencies of each score above 50, we need to consider the requirements of the program and the size of the input data.
Program requirements:
- The program needs to store the frequencies of each score above 50.
- The scores are in the range (0,100).
- There are 500 students.
Size of input data:
- There are 500 integers representing the scores of the students.
- The scores are in the range (0,100).
Based on the above information, the best way to store the frequencies would be an array of 50 numbers. Here's why:
Explanation:
1. The program needs to store the frequencies of each score above 50. Since the scores are in the range (0,100), the possible scores above 50 are 51, 52, ..., 100. There are 50 possible scores above 50.
2. Storing the frequencies in an array allows for efficient and direct access to each frequency based on the score. The index of the array represents the score, and the value at that index represents the frequency.
3. An array of 50 numbers is sufficient to store the frequencies of each score above 50. Since there are no scores above 100, there is no need to allocate additional space for scores that do not exist.
4. Using an array of 100 numbers would be wasteful as it would allocate extra space for scores that are not present in the input data.
5. Using an array of 500 numbers would not be efficient as it would allocate more space than necessary. It would also be confusing to map the index of the array to the corresponding score.
6. Using a dynamically allocated array of 550 numbers would also allocate more space than necessary. Additionally, dynamic allocation introduces complexity and overhead that is not required for this problem.
Therefore, the best way to store the frequencies of each score above 50 would be an array of 50 numbers.
