You’re interviewing for your dream job at an ecological ethical tech company with healthy snacks. You already passed 28 stages of interviews, and your final interviewer asks you to design a binary search tree data structure that performs INSERT operations in O( √ log n) time using a comparison-based algorithm. Design such a data structure or prove that this is impossible.

Interleave Strings

Given two strings, write a program to merge the given two strings by adding characters in alternating order, starting with the first string. If a string is longer than the other, append the additional characters onto the end of the merged string.Input

The first line of input will contain a string.

The second line of input will contain a string.

The strings may contain special characters, digits and letters.Output

The output should be the merged stringExplanation

For example, if the given strings are "abc" and "pqrs", then alternating characters from each string are merged as "a" from "abc", "p" from "pqr", "b" from "abc" and so on ..., resulting in the merged string "apbqcr".

input:

5

0 -2

3 6

4 7

1 -3

expected output : 7x^4 + 6x^3 - x^2 - 3x - 2

your output: 7x^4 + 6x^3 - 1x^2 - 3x - 2

for this code this is the error

and i am using python 3.9

Implement the following hierarchy.

· Make Shape, TwoDimensionalShape, and ThreeDimensionalShape as abstract class

Given polynomial, write a program that prints polynomial in Cix^Pi + Ci-1x^Pi-1 + .... + C1x + C0 format.

input : 5

0 2

1 3

2 1

4 7

expected output : 7x^4 + 6x^3 - x^2 - 3x - 2
    your output:  7x^4 + 6x^3 - 1x^2 - 3x - 2

please explain this why this is again show error

i am using python 3.9 version
