What is the best data type to use for currency in C#?
The best datatype to use for currency in C# is decimal. The decimal type is a 128-bit data type suitable for financial and monetary calculations. The decimal type can represent values ranging from 1.0 * 10^-28 to approximately 7.9 * 10^28 with 28-29 significant digits. To initialize a decimal variable, use the suffix m or M.decimal b = 2.1m;The below example shows the min and max value of decimal.Exampleusing System; namespace DemoApplication{ public class Program{ public static void Main(){ Console.WriteLine($"Deciaml Min Value: {decimal.MinValue}"); Console.WriteLine($"Deciaml Max Value: {decimal.MaxValue}"); ...
Read MoreCaesar Cipher in Python
Suppose we have a lowercase alphabet string s, and an offset number say k. We have to replace every letter in s with a letter k positions further along the alphabet. We have to keep in mind that when the letter overflows past a or z, it gets wrapped around the other side.So, if the input is like "hello", k = 3, then the output will be "khoor"To solve this, we will follow these steps −Define a function shift(). This will take ci := ASCII of (c) - ASCII of ('a')i := i + ki := i mod 26return character ...
Read MoreMaximize the maximum among minimum of K consecutive sub-arrays in C++
Given the task is to divide an array arr[] into K consecutive sub-arrays and find the maximum possible value of maximum among the minimum of the K consecutive sub-srrays.Input arr[]={2, 8, 4, 3, 9, 1, 5}, K=3Output 9Explanation − The 3 consecutive sub arrays that can made are: {2, 8, 4, 3}, {9}, and {1, 5}The minimum values out of all these arrays are: (2, 9, 1)The maximum value out of these three is 9.Input arr[] = { 8, 4, 1, 9, 11}, K=1Output 11Approach used in the below program as followsIf we look at the task, it can be divided into 3 cases ...

Suppose we have a list of words, we have to concatenate them in camel case format.So, if the input is like ["Hello", "World", "Python", "Programming"], then the output will be "helloWorldPythonProgramming"To solve this, we will follow these steps −s := blank stringfor each word in words −make first letter word uppercase and rest lowercaseconcatenate word with sret := s by converting first letter of s as lowercasereturn retLet us see the following implementation to get better understanding −Exampleclass Solution: def solve(self, words): s = "".join(word[0].upper() + word[1:].lower() for word in words) return s[0].lower() ...
Read MoreMaximum difference of indices (i, j) such that A[i][j] = 0 in the given matrix in C++
We are given with a matrix of size n x n and a condition that a[i][j] = 0 and the task is to calculate the maximum difference of indices having a[i][j] = 0. So, we can clearly state that there must be at least one zero in a matrix.Input int matrix[][] = { {0, 1, 1}, {0, 0, 0}, {4, 5, 1}}Output −Maximum difference of indices (i, j) such that A[i][j] = 0 in the given matrix is −Explanation − we have element 0 at matrix[0][0], matrix[1][0], matrix[1][1] and matrix[1][2]. So the maximum difference of indices will be ...
Read MoreFind smallest range containing elements from k lists in C++
Suppose we have k different lists. The elements are sorted. We have to search the smallest range that includes at least one number from each of the k different lists. Here the range [a, b] is smaller than range [c, d] when b-a < d-c or a < c if b-a == d-c.So if the input is like [[4, 10, 15, 25, 26], [0, 9, 14, 20], [5, 18, 24, 30]], then the output will be [14, 18]To solve this, we will follow these steps −minRange := inf, maxRange := -inf, rangeSize := inf, tempMinRange := inf, tempMaxRange := -infn ...
Read MoreCell fusion in Python
Suppose we have a list of numbers called cells; this list is representing sizes of different cells. Now, in each iteration, the two largest cells a and b interact according to these rules: So, If a = b, they both die. Otherwise, the two cells merge and their size becomes floor of ((a + b) / 3). We have to find the size of the last cell or return -1 if there's no cell is remaining.So, if the input is like [20, 40, 40, 30], then the output will be 16, in first iteration, 40 and 40 will die, then ...
Read MoreFind sub-arrays from given two arrays such that they have equal sum in Python
Suppose we have two arrays P and Q whose size are N, they are holding numbers 1 to N. We have to find sub-arrays from the given arrays so that they have equal sum. Finally return the indices of such sub-arrays. If there is no solution, then return -1.So, if the input is like P = [2, 3, 4, 5, 6], Q = [9, 3, 2, 6, 5], then the output will be Indices in first array : 0, 1, 2 and indices in second array: 0, so P[0..2] = 2 + 3 + 4 = 9 and Q[0] = ...
Read MoreChanging Directions in Python
Suppose we have a list of numbers called nums, we have to find the number of times that the list changes from positive-to-negative or negative-to-positive slope.So, if the input is like [2, 4, 10, 18, 6, 11, 13], then the output will be 2, as it changes the direction at 10 (positive-to-negative), and then at 6 (negative-to-positive).To solve this, we will follow these steps −To solve this, we will follow these steps −for i in range 1 to size of nums - 1, doif nums[i-1] < nums[i] > nums[i+1] or nums[i-1] > nums[i] < nums[i+1], thencount := count + 1return ...
Read MoreProgram to find greater value between a^n and b^n in C++
In this tutorial, we will be discussing a program to find greater value between a^n and b^n.For this we will be provided with three numbers. Our task is to calculate a^n and b^n and return back the greater of those values.Example#include using namespace std; //finding the greater value void findGreater(int a, int b, int n){ if (!(n & 1)) { a = abs(a); b = abs(b); } if (a == b) cout b) cout
