Count() is a built-in function is Golang that can be used to count the number of non-overlapping instances of a character/string in a string.Syntaxfunc Count(s, sep string) intWhere, s – Original Stringsep – Substring which we want to count.It returns an Integer value.ExampleThe following example demonstrates how you can use the Count() function in a Go program.package main import (    "fmt"    "strings" ) func main() {    // Initializing the Strings    x := "Golang Programming Language"    y := "Language"       // Display the Strings    fmt.Println("First String:", x)    fmt.Println("Second String:", y)   ...

To integrate a Hermite_e series, use the hermite_e.hermeint() method in Python. The 1st parameter, c is an array of Hermite_e series coefficients. If c is multidimensional the different axis correspond to different variables with the degree in each axis given by the corresponding index. The 2nd parameter, m is an order of integration, must be positive. (Default: 1)The 3rd parameter, k is an integration constant(s). The value of the first integral at lbnd is the first value in the list, the value of the second integral at lbnd is the second value, etc. If k == [] (the default), all ... Read More

To evaluate a Legendre series at points x, use the polynomial.legendre.legval() method in Python Numpy. The 1st parameter is x. If x is a list or tuple, it is converted to an ndarray, otherwise it is left unchanged and treated as a scalar. In either case, x or its elements must support addition and multiplication with themselves and with the elements of c.The 2nd parameter, C, an array of coefficients ordered so that the coefficients for terms of degree n are contained in c[n]. If c is multidimensional the remaining indices enumerate multiple polynomials. In the two dimensional case the ... Read More

Golang has a built-in string function called ContainsAny() that we can use to check whether a specified string is present in a given string or not.ContainsAny() is completely different from Contains().Contains() is used to detect if a string contains a substring.ContainsAny() is used to detect if a string contains any characters in the provided string. Even if one character of the specified string is present in the original given string, then it returns True, else False.Syntaxfunc ContainsAny(s, chars string) boolWhere, s – Original Stringchars string – Substring where we define the string or characters.It returns a Boolean value.ExampleContainsAny() is case-sensitive, ...

To differentiate a Hermite_e series, use the hermite_e.hermeder() method in Python. The 1st parameter, c is an array of Hermite_e series coefficients. If c is multidimensional the different axis correspond to different variables with the degree in each axis given by the corresponding index.The 2nd parameter, m is the number of derivatives taken, must be non-negative. (Default: 1). The 3rd parameter, scl is a scalar. Each differentiation is multiplied by scl. The end result is multiplication by scl**m. This is for use in a linear change of variable. (Default: 1). The 4th parameter, axis is an Axis over which the ... Read More

To differentiate a Legendre series, use the polynomial.laguerre.legder() method in Python. Returns the Legendre series coefficients c differentiated m times along axis. At each iteration the result is multiplied by scl.The 1st parameter, c is an array of Legendre series coefficients. If c is multidimensional the different axis correspond to different variables with the degree in each axis given by the corresponding index. The 2nd parameter, m is the number of derivatives taken, must be non-negative. (Default: 1). The 3rd parameter, scl is a scalar. Each differentiation is multiplied by scl. The end result is multiplication by scl**m. This is ... Read More

Golang has a built-in string function called Compare() that we can use to compare two strings. Here strings are compared using the lexicographical order.Syntaxfunc Compare(a, b string) intReturn TypesIf the strings (a == b), it returns 0.If the strings (a > b), then it returns 1If the strings (a < b), then it returns -1ExampleLet us consider the following example −package main // importing fmt and strings import (    "fmt"    "strings" ) func main() {    // Intializing the variables    var a1 = "a"    var a2 = "b"    var a3 = "welcome"    var a4 ...

Golang has a set of built-in string functions that we can utilize to perform different types of operations on string data. Contains() is such a function that can be used to search whether a particular text/string/character is present in a given string. If the text/string/character is present in the given string, then it returns True; else it returns False.Syntaxfunc Contains(s, substr string) boolWhere, s is the original string and substr is the string which is to be checked with the original string.ExampleThe following example demonstrates how Contains() works −package main // importing fmt and strings import (    "fmt"   ...

To evaluate a 2-D Hermite_e series on the Cartesian product of x and y, use the hermite.hermegrid2d(x, y, c) method in Python. The method returns the values of the two dimensional polynomial at points in the Cartesian product of x and y.The parameters are x, y. The two dimensional series is evaluated at the points in the Cartesian product of x and y. If x or y is a list or tuple, it is first converted to an ndarray, otherwise it is left unchanged and, if it isn’t an ndarray, it is treated as a scalar.The parameter, c is an ... Read More
