A palindrome permutation is a string that, when rearranged, can form a palindrome. Given an input string, determine if any permutation of the string is a palindrome. For example, "civic" is already a palindrome, and "ivicc" can be rearranged to "civic", but "hello" cannot be rearranged to form a palindrome. A palindro...	<think> Okay, I've got this problem to solve. Let's see what it's about. So, I need to determine if any permutation of a given string can form a palindrome. Hmm, palindromes are strings that read the same forwards and backwards. So, the idea is to check whether the characters in the string can be rearranged into such a...

You are given a grid with R rows and C columns. Each cell in the grid is either empty (denoted by '.') or contains a wall (denoted by '#'). You start at the top-left cell of the grid and want to reach the bottom-right cell. You can move up, down, left, or right, but you cannot pass through walls. Implement a function t...	<think> Okay, so I need to solve this problem where I have a grid, and I have to find the shortest path from the top-left corner to the bottom-right corner, moving only through the empty cells. Hmm. Wait, the grid can be quite large—up to 1000x1000. So any solution must be efficient. I remember that BFS (Breadth-First...

Write a function that takes a string containing a mix of letters and digits. The function should return a new string with all the digits sorted in non-decreasing order at the beginning, and the letters in their original order at the end of the string. Ignore any non-alphanumeric characters in the input string. Example...	<think> Okay, so I have to write a Python function called sort_digits that takes a string and returns a new string.

You are given a single integer n. Your task is to calculate the sum of the squares of the first n natural numbers. For example: n = 3 then the sum of squares is 1^2 + 2^2 + 3^2 = 14 Input: A single integer n. Output: Print out the sum of squares of the first n natural numbers. Constraints: 1 ≤ n ≤ 1000000000 (10^9)...	<think> Okay, I need to solve this problem where I have to find the sum of squares of the first n natural numbers. The input is a single integer n, and I have to output the sum. The constraints say that n can be as large as 10^9, so a brute-force approach with a loop would be way too slow. I remember that there's a mat...	[ { "from": "human", "value": "You are given a single integer n.

Given a set of three positive integers representing the side lengths of a triangle, determine if the triangle is a right-angled triangle.

Given an array of integers, the task is to find out the sum of elements which are not the maximum or the minimum element in the given array. Example 1: Input: N = 5 arr[] = {3, 1, 2, 5, 4} Output: 5 Explanation: The elements excluding the maximum (5) and minimum (1) are 3, 2, 4. Their sum is 5+4+3 = 12.
