Q1. How Quick sort works
Ans. 
Quick sort is a divide-and-conquer algorithm that sorts an array by selecting a pivot element and partitioning the array around the pivot.
• Select a pivot element from the array

• Partition the array into two sub-arrays: elements less than the pivot and elements greater than the pivot

• Recursively apply the same process to the sub-arrays

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

Q3. Writecodefor binary search
Ans. 
Binary search is a divide and conquer algorithm that efficiently finds the target value within a sorted array.
• Start by defining the low and high indices of the array.

• Calculate the mid index as (low + high) / 2.

• Compare the target value with the value at the mid index and adjust the low and high indices accordingly.

• Repeat the process until the target value is found or the low index surpasses the high index.
