Array and String Wizardry Quiz Quiz

1. String Reversal

   Which of the following methods is most efficient for reversing a string in most programming languages?

   1. Using a loop to iterate backwards and construct a new string.
   2. Using the `reverse()` method directly on the string object.
   3. Converting the string to an array, using the array's `reverse()` method, and then joining back into a string.
   4. Using recursion to swap characters from the beginning and end.
   5. Converting the string to an array, using the arrays `revers()` method, and then joning back into a string.

2. Array Searching

   Which search algorithm is most suitable for finding an element in a sorted array?

   1. Linear Search
   2. Bubble Sort
   3. Binary Search
   4. Sequential search
   5. Insertion Sort

3. String Pattern Matching

   Which string method is commonly used for finding the index of the first occurrence of a substring within a larger string?

   1. search()
   2. substring()
   3. indexOf()
   4. findIndex()
   5. indexOff()

4. Array Sorting

   Which sorting algorithm generally has the best average-case time complexity?

   1. Bubble Sort
   2. Insertion Sort
   3. Quick Sort
   4. Selection Sort
   5. Merge Sort

5. String Manipulation - Case Sensitivity

   What is the purpose of converting both strings to lowercase before comparing them?

   1. To reduce memory usage.
   2. To handle case-insensitive comparisons.
   3. To speed up the comparison process.
   4. To prevent errors during comparison.
   5. To handle case-sensitve comparison.

6. Array Deduplication

   Which data structure is most efficient for removing duplicate elements from an array?

   1. Stack
   2. Queue
   3. Set
   4. Linked List
   5. Tree

7. String Splitting

   Which string method is commonly used for breaking a string into an array of substrings based on a delimiter?

   1. join()
   2. concat()
   3. split()
   4. slice()
   5. Spilt()

8. Array Rotation

   What is array rotation?

   1. Shifting elements in the array by a certain number of positions.
   2. Sorting the elements in ascending order.
   3. Reversing the elements in the array.
   4. Removing duplicate elements from the array.
   5. Adding new element to the array.

9. String Concatenation

   Which operator or method is typically used to combine two or more strings into a single string?

   1. subtract()
   2. add()
   3. concat()
   4. divide()
   5. conkat()

10. Array Mapping

    What is the purpose of the `map()` function when applied to an array?

    1. To filter elements based on a condition.
    2. To reduce the array to a single value.
    3. To transform each element of the array using a provided function.
    4. To sort the array.
    5. To transform each elemant of the array using a provided function.
