Suppose we have a number n, we have ot find the nth value from the sequence. The sequence is like below −xxyxxyxxyyxxyxxxyyxyyxyyxyyxyyxyy...To generate the next value, we have to follow these rules, starting with xxy as the first term −When we are at the start of the pattern, double it(concatenate ...

Suppose we have two numbers n and m representing a board of size n x m. We also have an unlimited number of 1 x 2 dominos. We have to find the maximum number of dominos that can be placed on the board such that they don't overlap and every ... Read More

Suppose we have a list of votes, where each element in the list has two elements [c_id, v_id], the c_id is the candidate id and v_id is the voter id. We have to check whether any voter has voted more than once or not.So, if the input is like [[5, ... Read More

Suppose we have a string called animals and another string called dinosaurs. Every letter in animals represents a different type of animal and every unique character in dinosaurs string represents a different dinosaur. We have to find the total number of dinosaurs in animals.So, if the input is like animals ... Read More

Suppose we have a list of numbers called nums, we have to find the number of elements x there are such that x + 1 exists as well.So, if the input is like [2, 3, 3, 4, 8], then the output will be 3To solve this, we will follow these ... Read More

Suppose we have a number n representing the length of an n x n board. We have to delete all cells that are diagonal to one of the four corners and return the number of empty cells.So, if the input is like n = 4, XOOXOXXOOXXOXOOXThen the output will be ... Read More

Suppose we have a number n, we have to find the nth term of Connell sequence. The Connell sequence is as follows: 1. Take first odd integer: 1 2. Take next two even integers 2, 4 3. Then take the next three odd integers 5, 7, 9 4. After that ... Read More

Suppose we have two strings s0 and s1, they are representing a sentence, we have to find the number of unique words that are shared between these two sentences. We have to keep in mind that, the words are case-insensitive so "tom" and "ToM" are the same word.So, if the ... Read More

Suppose we have a matrix, we have to sort each of the columns in ascending order.So, if the input is like1121316641118then the output will be1646118112131To solve this, we will follow these steps −R := row count of matrix, C := column count of matrixres := matrix of same size as ... Read More

Suppose we have a positve integer n, we have to find the length of its Collatz sequence. As we know Collatz sequence is generated sequentially where n = n/2 when n is even otherwise n = 3n + 1. And this sequence ends when n = 1.So, if the input ... Read More
