  • Ans. 

    Binary Search has a time complexity of O(log n) and is derived from dividing the search space in half at each step.

    • Binary Search is a search algorithm that works on sorted arrays.

    • It starts by comparing the target value to the middle element of the array.

    • If the target value is smaller, the search continues on the lower half of the array.

    • If the target value is larger, the search continues on the upper half of the array.

  • Q3. Write code for QuickSort
  • Ans. 

    QuickSort is a sorting algorithm that uses divide and conquer approach.

    • Choose a pivot element from the array

    • Partition the array into two sub-arrays, one with elements less than the pivot and one with elements greater than the pivot

    • Recursively apply the above steps to the sub-arrays

    • Combine the sorted sub-arrays to get the final sorted array
