The Type.Equals() method in C# determines if the underlying system type of the current Type is the same as the underlying system type of the specified Object or Type.Syntaxpublic virtual bool Equals (Type o); public override bool Equals (object o);Above, the parameters are the object whose underlying system type is to be compared with the underlying system type of the current Type.Let us now see an example to implement the Type.Equals() method −using System; public class Demo {    public static void Main(string[] args) {       Type val1 = typeof(System.UInt16);       Type val2 = typeof(System.Int32);   ...

The Tuple class represents a 7-tuple, which is called septet. A tuple is a data structure that has a sequence of elements.It is used in −Easier access to a data set.Easier manipulation of a data set.To represent a single set of data.To return multiple values from a methodTo pass multiple values to a methodIt has seven properties −Item1− Get the value of the current Tuple object's first component.Item2− Get the value of the current Tuple object's second component.Item3− Get the value of the current Tuple object's third component.Item4− Get the value of the current Tupleobject's fourth component.Item5− Get the value ...

Pandas is the important package for data analysis in Python. There are different versions available for Pandas. Due to some version mismatch, it may create some problems. So we need to find the version numbers of the Pandas. We can see them easily using the following code.We can use the command like below, to get the version −pandas.__version__Example>>> import pandas as pd >>> print(pd.__version__) 0.25.2 >>>We can also get the version of the dependencies using the function like below −pandas.show_versions() >>> pd.show_versions() INSTALLED VERSIONS ------------------ commit : None python : 3.7.1.final.0 python-bits : 64 OS : Windows OS-release : 7 ...

The Math.Exp() method in C# is used to return e raised to the specified power.Syntaxpublic static double Exp (double val);Here, Val is the power.If Val equals NaN or PositiveInfinity, that value is returned. However, if d equals NegativeInfinity, 0 is returned.Let us now see an example to implement Math.Exp() method −Exampleusing System; public class Demo {    public static void Main(){       Console.WriteLine(Math.Exp(0.0));       Console.WriteLine(Math.Exp(Double.PositiveInfinity));       Console.WriteLine(Math.Exp(Double.NegativeInfinity));    } }OutputThis will produce the following output −1 ∞ 0Let us see another example to implement Math.Exp() method −Exampleusing System; public class Demo {    public ...

We have to take a number Y, we will find smallest number X, such that X! contains at least Y number of training zeros. For example, if Y = 2, then the value of X = 10. As X! = 3228800. It has Y number of zeros.We can solve this using binary search. The number of trailing zeros in N! is given by the count of the factors 5 in N!. X can be found using binary search in range [0, 5*Y]Example #include using namespace std; int factorCount(int n, int X) {    if (X < n)       ... Read More

Suppose we have an array of n elements. We have to find the first, second smallest elements in the array. First smallest is the minimum of the array, second smallest is minimum but larger than the first smallest number.Scan through each element, then check the element, and relate the condition for first, and second smallest elements conditions to solve this problem.Example #include using namespace std; int getTwoSmallest(int arr[], int n) {    int first = INT_MAX, sec = INT_MAX;    for (int i = 0; i < n; i++) {       if (arr[i] < first) {     ...
