  • Ans. 

    Divide a rectangle of M x N into smaller rectangles of M1 x N1 to minimize wastage.

    • Start by dividing the rectangle horizontally or vertically based on the dimensions of the smaller rectangles.

    • Continue dividing each resulting sub-rectangle until no further division is possible.

    • Consider the dimensions of the smaller rectangles and the remaining space to minimize wastage.

  • Ans. 

    The number of 'BB' occurrences at the Nth iteration of the transformation sequence.

  • Q1. 1)There are three types of balls arranged linearly in a random order Red, Green and Blue. Now your job is to sort them so that the Red balls are in front follwed by the Green balls and the Blue balls are p...
  • Ans. 

    Sorting an array of 0, 1 and 2 can be done in O(n) using two pointers.

    • Use two pointers, one for 0 and one for 2, and a current pointer to traverse the array

    • If the current pointer encounters a 0, swap it with the 0 pointer and move both pointers to the right

    • If the current pointer encounters a 2, swap it with the 2 pointer and move the 2 pointer to the left

    • Repeat until the current pointer meets the 2 pointer

  • Ans. 

    Algorithm to find if a number is present in a sorted n x n matrix with linear time complexity.

    • Start with the top right element

    • Compare the element with x

    • If equal, return its position

    • If e < x, move down (if out of bounds, return false)

    • If e > x, move left (if out of bounds, return false)

    • Repeat till element is found or returned false

  • Ans. 

    The problem is to find non-empty subsets of a given set of integers whose sum is zero.

    • The problem is a special case of the knapsack problem and is known to be NP-Complete.

    • A brute-force approach would involve generating all subsets and checking their sums.

    • The brute-force approach has an exponential time complexity.

    • There is no known polynomial time solution for this problem.

  • Answered by AI
  • Q5. 5)Create a data structure where inserting, deleting and finding the minimum element all have O(1) time. i said we can use augmented stack where with each element we can augment the minimum element along wi...
  • Ans. 

    Data structure with O(1) insert, delete, and find min without creating new structures

    • Use two stacks, one for actual data and one for minimum values

    • When inserting, push the value onto the data stack and push the minimum of the new value and the top of the minimum stack onto the minimum stack

    • When deleting, pop from both stacks

    • When finding the minimum, return the top of the minimum stack

King told him to find the largest continuous patch of water.so that he can send his people over there.As our Aladdin is modern, but not a good programmer, he wants your help. Help him out by printing out the largest area water patch available on map.
