- Q1. Find Square root of an integer
You are given an integer ‘A’. Your task is to find the greatest non-negative integer whose square is less than or equal to ‘A’.
Square of a number is the product of the num...
- Ans.
The Simple Approach is to find the floor of the square root, try with all-natural numbers starting from 1. Continue incrementing the number until the square of that number is greater than the given number.
Algorithm :
1. Create a variable (counter) i and take care of some base cases, i.e when the given number is 0 or 1.
2. Run a loop until i*i <= n , where n is the given number. Increment i by 1.
3. The floor of t... - Q2. Find the minimum element in a sorted and rotated array
You're given a sorted array that has now been rotated 'K' times, which is unknown to you. Rotation here means that every element is shifte...
- Ans.
The brute force solution is to traverse the entire array and find the minimum. Time Complexity : O(N)
The efficient approach is to use Binary Search. The following pattern can be observed :
• The minimum element is the only element whose previous is greater than it. If there is no previous element, then there is no rotation (the first element is minimum). We check this condition for the middle element by comp...

- Q1. Find square root of integer
- Ans.
Use binary search to find the square root of an integer.
Start with low=0 and high=x.
While low<=high, calculate mid=(low+high)/2.
If mid*mid==x, return mid.
If mid*mid
If mid*mid>x, set high=mid-1.
Return high as the floor of the square root.
- Q2. Find number in sorted rotated array
- Ans.
Find a given number in a sorted rotated array.
Use binary search to find the pivot point where the array is rotated.
Determine which half of the array the target number may be in.
Perform binary search on the appropriate half of the array to find the target number.
