A matrix probability question in C?
The matrix probability question Calculates the probability that whether an element will be inside the given matrix after taking N steps and any direction. This means we need to find what is the probability of an element not going out of the scope of the matrix even after moving N positions in any direction.In this problem, we are free to move the matrix element in all four directions (left, right, up, down). And the probability of moving elements is same 0.25 or 1/4.The program will return 0 if the element steps out otherwise not.Example#include int isSafe(int x, int y, ...
Read MoreAngle between two Planes in 3D in C++?
For learning about the angle between two planes in 3D, we need to learn about planes and angles.Plane is a two-dimensional surface that extends to infinity.Angle is the space in degrees between two lines and surfaces which intersect at a point.So, in this problem we need to find the angle between two 3D planes. For this we have two planes that intersect each other and we need to find the angle at which the are intersecting each other.To calculate the angle between two 3D planes, we need to calculate the angle between the normal's of these planes.Here, we have two ...
Read MoreArray elements with prime frequencies in C++?
Array is a container of elements of same data type.Prime Frequencies means that the number of occurrence of the element of the array is a prime number.So, based on these definitions the problem to find array elements with prime frequencies. We are given a string of array. We have to find the frequency of characters and check if frequency is prime and then count elements that have prime frequencies.Let’s take an example, Input: str = “helloworld” Output: 2ExplanationCount of occurrences of characters are −h -> 1 e -> 1 l -> 3 o -> 2 w-> 1 r -> 1 ...
Read MoreAlternative Sorting in C++
Sorting the elements of an integer array in such a way that the first element is the maximum of the array and the second element of the sorted array is the minimum, the third one is the second minimum, the fourth one is the second maximum of the array and goes on.Let’s take an example to understand the concept better, Input : 4 1 8 2 9 3 7 Output : 9 1 8 2 7 3 4 Explanation : The elements in a sorted way is 1 2 3 4 7 8 9. Now, let’s create it in ...
Read MoreSplit the array into equal sum parts according to given conditions in C++
Here we will see one problem. Suppose one array arr is given. We have to check whether the array can be split into two parts, such that −Sub of both sub-arrays will be the sameAll elements, which are multiple of 5, will be in the same groupAll elements which are multiple of 3, but not multiple of 5, will be in the same groupAll other elements will be in other groups.Suppose the array elements are {1, 4, 3}, then this can be split, because the sum of {1, 3} is the same as the sum of {4}, and the groups ...
Read MoreMaximum Consecutive Zeroes in Concatenated Binary String in C++
Suppose we have a binary string of length n, another value say k is given. We have to concatenate the binary string k times. Then we have to find the maximum number of consecutive 0s in the concatenated string. Suppose binary string is “0010010”, and k = 2, then after concatenating the string k times, it will be “00100100010010”. So the maximum number of consecutive 0s is 3.The approach is simple. If the number has all 0s, then the answer will be n * k. If the string contains ones, then the result will be either the max length of ...
Read MoreMaximum GCD from Given Product of Unknowns in C++
Suppose we two integers N and P. The P is the product of N unknown integers. We have to find the GCD of those integers. There can be different groups of integers possible, that will give the same result. Here we will produce GCD, which is maximum among all possible groups. Suppose N = 3, and P = 24, then different groups will be like {1, 1, 24}, {1, 2, 12}, {1, 3, 8}, {1, 4, 6}, {2, 2, 6}, {2, 3, 4}. The GCDs are: 1, 1, 1, 1, 2, 1. So answer is 2 here.The technique us like, ...
Read MoreProgram to convert KiloBytes to Bytes and Bits in C++
Given with the input as KiloBytes and the task is to convert the given input into number of bytes and bits.Bit − In computers, bit is the smallest unit represented with two integer value 0 and 1 and all the information in computer is processed as a sequence of these two digits.N-bits = 2 ^ N patterns, where N can be any integer value starting from 1.Byte − In computers, byte is represented with 8 bits. Byte is capable of holding one character to numbers ranging between 0 and 255.1 byte = 8 bitsWhich means 2 ^ 8 patterns which ...
Read MoreProgram to convert IP address to hexadecimal in C++
Given with the input as an IP address value and the task is to represent the given IP address as its hexadecimal equivalent.What is IP addressIP address or Internet protocol is a unique number to that uniquely describes your hardware connected to a network. Internet means over the network and protocol defines the set of rules and regulations that must be followed for connection. Because of IP address only it is possible for a system to communicate with another system over a network. There are two versions of IP that are −IPv4(Internet Protocol Version 4)IPv6(Internet Protocol Version 6)IP address is ...
Read MoreProgram for Fahrenheit to Kelvin conversion in C++
Given with temperature ‘n’ in Fahrenheit and the challenge is to convert the given temperature to kelvin and display it.ExampleInput 1-: 549.96 Output -: Temperature in fahrenheit 549.96 to kelvin : 561.256 Input 2-: 23.45 Output -: Temperature in fahrenheit 23.45 to kelvin : 268.4For converting the temperature from Fahrenheit to Kelvin, there is a formula which is given belowK = 273.5 + ((F - 32.0) * (5.0/9.0))Where, K is temperature in kelvin and F is temperature in FahrenheitApproach used below is as follows −Input temperature in a float variable let’s say FahrenheitApply the formula to convert the temperature into ...
