Maximum Pairs of Bracket Sequences which can be concatenated to form a Regular Bracket Sequence
Regular Bracket Sequence means a string that contains the parentheses of both opening and closing types and results in properly closed brackets. The given sequence may be properly symmetrical and maybe not. In this problem, we are given a list of string that contains the bracket sequences and we have to find the number of pairs that can be concatenated to a single regular bracket sequence. Sample Examples Input 1 string arr[] = {“)()”, “()(“, “()()”, “(())”} Output: 2 Explanation − For the first and second strings we can concatenate the first string after the second string resulting in the ...
Read MoreMaximum count of 0s between two 1s in the given range for Q queries
A binary string is a string that only contains the zeroes and ones as the different characters in them. We are given a binary string and an array of a given length that will contain the pairs. Each pair defines the range, and in that range, we have to return the maximum number of zeros lying between two ones. We will implement two approaches one is the naive approach and another is the efficient approach. Let’s understand with the help of example Input String str = ‘1011010110’ Array Q[][] = {{0, 2}, {2, 5}, {0, 9}} Output: 1 1 3 ...
Read MoreMinimum cost for constructing the subsequence of length K from given string S
We will be given a string of length n, an integer k, and an integer array of length 26. The integer array defines the cost of each lowercase character and the string will contain only lowercase letters. We have to create a subsequence of length k from the given string at the minimum possible cost. We will use sorting to solve the problem and will implement a code with a full explanation. Sample Examples Input 1 Given string: acbcbac Given number: 4 Given array: {2, 3, 1, 2, 4, 5, 5, 6, 6, 2, 1, 0, 4, 3, 5, ...
Read MoreFind an N-length Binary String having maximum sum of elements from given ranges
We will be given an array that will contain the pairs which represent the range and their value will range from 0(inclusive) to N(exclusive). Here, N is the size of the binary string which we have to return as the answer. For all the given ranges we have to maximize the sum of the product of the frequencies of zero and one. We will implement two approaches one is the naive approach by finding all the strings and another is the efficient solution. Sample Examples Input 1 Given array: {{1, 3}, {2, 4}, {2, 5}} Length of string: 6 Output ...
Read MoreSort an array by swapping adjacent elements from indices that contains ‘1’ in a given string
Sorting an array means ordering all the elements of the array in increasing order. Sorting an array by swapping adjacent elements means we can only swap elements that are adjacent to each other but we can swap adjacent elements any number of times. We will be given a binary string that will contain only two types of characters ‘0’ and ‘1’. If any character is ‘0’ in the given string then we cannot swap the element present at that index of the array with adjacent elements. Sample Examples Input 1 Given array: {1, 4, 3, 2, 5, 7, 6} Given ...
Read MoreMinimum number of flipping adjacent bits required to make given Binary Strings equal
A binary string is a string that contains only two different types of characters 0 and 1. We will be given two binary strings of the same length and our task is to make both of them equal by toggling two adjacent characters of the first string. Also, we have to do this in a minimum number of operations as possible. If it is not possible to convert the first string to the second string then return -1. Sample Example Input 1 string1: 101001 string 2: 100110 Output: 2 Explanation − We can toggle the second index character and the ...
Read MoreDifference between Control Structure and Control Statement
Control structures and control statements are essential concepts in programming. A control structure could be a piece of code that controls the stream of execution of a program based on certain conditions. On the other hand, a control explanation could be a statement that performs a particular activity based on certain conditions. In this article, we'll investigate the difference between control structures and control explanations, their utilization, and how they contribute to the general usefulness of a program. We'll too talk about a few illustrations of commonly utilized control structures and articulations of completely different programming dialects. Control Structure A ...
Read MoreDifference between Fine-Grained and Coarse-Grained SIMD Architecture
SIMD stands for Single Instruction Multiple Data. A type of computer architecture in which a single instruction can be executed on multiple pieces of data in parallel is referred to as a SIMD (Single Instruction Multiple Data) architecture. Therefore, SIMD architecture is primarily used in parallel processing application where large amounts of data required to be processed at the same time. In the case of SIMD, a single instruction is executed on a group of data that are stored in contiguous memory locations. SIMD architecture is used in a variety of applications audio and video processing, simulations, 3D graphics processing, ...
Read MoreMax count of N using digits of M such that 2 and 5, and, 6 and 9 can be treated as same respectively
Max count is a count which is the maximum possible. Here we have given an integer N and a string of integer M. Our task is to return the maximum count of making the number N using the digits of the string of integer M. Also given that, we can be treated 2 and 5, and, 6 and 9 can be same respectively. Sample Examples Input 1 N = 29 M = "2569783" Output 1: 2 Explanation − As 5 is the same as 2 and 6 is the same as 9 so we have a total of two ...
Read MoreFind the smallest number formed by inserting a given digit
Inserting a number in the given number means adding a new given digit in the given number either at the front, end, or in between the numbers. We have given a number and a digit and have to add the digit in the number in a way such that the resultant new number will be minimum as possible. We will convert the number into a string to make the work of insertion easy. Also, the given number can be negative also so we have to consider this case. Sample Examples Input1 Given number: 124 Given digit: 3 Output: 1234 ...
