Here is code for implementing a singly-linked list: class LinkedList { constructor(value) { this.head = { value: value, next: null, }; this.tail = this.head; this.length = 1; } append(value) { const newNode = { value: value, next: null, }; this.tail.next…
I recently start learning sql database, and I can't find the time complexity for the case where I have a huge amount of tables. For example, I have M tables [table_1, table_2, ..., table_m, ..., table_M], and each table has…
I want to create a function to compare a list of objects in the fast way for (let i = 0; i < posts.length - 1; i++) { for (let j = i + 1; j < posts.length; j++) {…
I am working with Office.js development, you don't need to know anything about it since the question relates more to Javascript. In Excel you can get a matrix of formulas with a function, that is an array of arrays. Usually…
I am wondering what BIG O would be in this case? I thought it was O(1) since it has fixed number of iteration (the array.length is fixed)... and even if in the worst case (3999), still the max iteration is…
I want to solve the problem: find all ordered pairs in an array where A[i] + A[j] = q , i != j for example: array = [1,3,3,3] q = 6 output = [[3,3], [3,3], [3,3], [3,3], [3,3], [3,3]] I…
What is the big O notation for the following code? _data.validatorInfo.result.validators.forEach((_validator) => { let del = { delegation: _data.delegations.result.delegation_responses.find( res => res.delegation.validator_address === _validator.operator_address ), validator: _validator, rewards: _data.totalRewards.result.rewards.find( re => re.validator_address === _validator.operator_address ) } result.delegations.push(del); }) Since it…
I am reading the book Artificial Intelligence: A Modern Approach. I came across this sentence describing the time complexity of uniform cost search: Uniform-cost search is guided by path costs rather than depths, so its complexity is not easily characterized…
