Missing Test Case - 2704. To Be Or Not To Be

by ADMIN 45 views

Problem Overview

The problem "To Be Or Not To Be" is a coding challenge that requires developers to write a function called expect that helps test their code. The function should take in any value val and return an object with two methods: toBe and notToBe. These methods should be used to compare the value of val with another value passed as an argument.

Problem Description

The toBe method should return true if the two values are equal, and throw an error "Not Equal" if they are not equal. On the other hand, the notToBe method should return true if the two values are not equal, and throw an error "Equal" if they are equal.

Language Used for Code

The problem does not specify a particular programming language to be used for the solution. However, we can assume that the solution should be written in a language that supports object-oriented programming and has a concept of methods.

Code Used for Submit/Run Operation

class Expect {
  constructor(val) {
    this.val = val;
  }

  toBe(otherVal) {
    if (this.val === otherVal) {
      return true;
    } else {
      throw new Error("Not Equal");
    }
  }

  notToBe(otherVal) {
    if (this.val !== otherVal) {
      return true;
    } else {
      throw new Error("Equal");
    }
  }
}

Expected Behavior

The expect function should return an object with the toBe and notToBe methods. When the toBe method is called with another value, it should return true if the two values are equal, and throw an error "Not Equal" if they are not equal. Similarly, when the notToBe method is called with another value, it should return true if the two values are not equal, and throw an error "Equal" if they are equal.

Test Cases

To test the expect function, we can write the following test cases:

const expect = new Expect(5);

console.log(expect.toBe(5)); // Should print: true
console.log(expect.toBe(10)); // Should throw an error: Not Equal

console.log(expect.notToBe(5)); // Should throw an error: Equal
console.log(expect.notToBe(10)); // Should print: true

Bug Description

The problem constraints and examples are not provided, but based on the problem description, we can assume that the expect function should work correctly for any value val and any other value passed as an argument.

Bug Category

The bug category for this problem is problem constraints and problem examples.

Solution

The solution to this problem is to write a function expect that takes in any value val and returns an object with the toBe and notToBe methods. The toBe method should return true if the two values are equal, and throw an error "Not Equal" if they are not equal. The notToBe method should return true if the two values are not equal, and throw an error "Equal" if they are equal.

Code Explanation

The code explanation for problem is as follows:

  • We define a class Expect with a constructor that takes in a value val.
  • The toBe method is defined to return true if the two values are equal, and throw an error "Not Equal" if they are not equal.
  • The notToBe method is defined to return true if the two values are not equal, and throw an error "Equal" if they are equal.

Time Complexity

The time complexity of this solution is O(1), as it involves a constant number of operations.

Space Complexity

The space complexity of this solution is O(1), as it involves a constant amount of space.

Conclusion

In conclusion, the problem "To Be Or Not To Be" requires developers to write a function expect that helps test their code. The function should take in any value val and return an object with the toBe and notToBe methods. These methods should be used to compare the value of val with another value passed as an argument. The solution to this problem is to write a function expect that takes in any value val and returns an object with the toBe and notToBe methods. The toBe method should return true if the two values are equal, and throw an error "Not Equal" if they are not equal. The notToBe method should return true if the two values are not equal, and throw an error "Equal" if they are equal.
