Check order of character in string using OrderedDict( ) in Python
When it is required to check the order of the character in the string, the ‘OrderedDict’ method can be used.Below is the demonstration of the same −Examplefrom collections import OrderedDict def check_order(my_input, my_pattern): my_dict = OrderedDict.fromkeys(my_input) pattern_length = 0 for key, value in my_dict.items(): if (key == my_pattern[pattern_length]): pattern_length = pattern_length + 1 if (pattern_length == (len(my_pattern))): return 'The order of pattern is correct' return 'The order of pattern is incorrect' my_input = 'Hi Mark' input_pattern = 'Ma' print("The ...
Read MoreGolang Program to Check if a Number is a Perfect Number
StepsRead an integer and store it in a variable.Initialize a variable to count the sum of the proper divisors to 0.Use a for loop and an if statement to add the proper divisors of the integer to the sum variable.Check if the sum of the proper divisors of the number is equal to the variable.Print the final result.Enter any number: 6The number is a Perfect number!Enter any number: 25The number is not a Perfect number!Examplepackage main import "fmt" func main(){ var n int fmt.Print("Enter any number: ") fmt.Scanf("%d", &n) sum1 := 0 for i:=1; i
Read MoreGolang Program to check if two numbers are Amicable Numbers
StepsRead two integers and store them in separate variables.Find the sum of the proper divisors of both the numbers.Check if the sum of the proper divisors is equal to the opposite numbers.If they are equal, they are amicable numbers.Print the final result.Enter number 1: 220Enter number 2: 284Amicable!Enter number 1: 349Enter number 2: 234Not Amicable!Examplepackage main import "fmt" func main(){ var a, b int fmt.Print("Enter first number: ") fmt.Scanf("%d", &a) fmt.Print("Enter second number: ") fmt.Scanf("%d", &b) sum1 := 0 for i:=1; i
Read MoreGolang Program to Find the Area of a Triangle Given All Three Sides
StepsRead all the three sides of the triangle and store them in three separate variables.Using the Heron's formula, compute the area of the triangle.Print the area of the triangle.Enter first side: 15Enter second side: 9Enter third side: 7Area of the triangle is: 20.69Enter first side: 5Enter second side: 6Enter third side: 7Area of the triangle is: 14.7ExplanationUser must enter all three numbers and store them in separate variables.First, the value of s is found which is equal to (a+b+c)/2Then, the Heron's formula is applied to determine the area of the triangle formed by all three sides.Finally, the area of the ...
Read MoreGolang Program to Find the Gravitational Force Acting Between Two Objects
StepsRead both the masses and the distance between the masses and store them in separate variables.Initialize one of the variables to the value of gravitational constant, G.Then, the formula f=(G*m1*m2)/(r**2) is used to determine the force acting between the masses.Rounding off up to two decimal places, print the value of the force.Enter the first mass: 1000000Enter the second mass: 500000Enter the distance between the centres of the masses: 20Hence, the gravitational force is: 0.08 NEnter the first mass: 90000000Enter the second mass: 7000000Enter the distance between the centres of the masses: 20Hence, the gravitational force is: 105.1 NExplanationUser must enter ...
Read MorePython dictionary with keys having multiple inputs
When it is required to create a dictionary where keys have multiple inputs, an empty dictionary can be created, and the value for a specific key can be specified.Below is the demonstration of the same −Examplemy_dict = {} a, b, c = 15, 26, 38 my_dict[a, b, c] = a + b - c a, b, c = 5, 4, 11 my_dict[a, b, c] = a + b - c print("The dictionary is :") print(my_dict)OutputThe dictionary is : {(15, 26, 38): 3, (5, 4, 11): -2}ExplanationThe required packages are imported.An empty dictionary is defined.The values for a specific key are specified.The output is displayed on the console.
Read MoreAnonymous function in Dart Programming
A function without a name is known as an anonymous function. They behave in the exact same manner as a normal named function would. The only difference between the named and an anonymous function is how different they are in syntax.Anonymous functions are used in Dart to form closures. An anonymous function contains a self-contained block of codes, also it can be passed as a parameter to another function as well.Anonymous function Syntax(parameterList){ // inner statement(s) }ExampleNow, let's consider a simple example of an anonymous function.Consider the example shown below −void main() { var fruits = ["Apple", "Mango", ...
Read MoreGolang Program to Print the Numbers in a Range (1, upper) without Using any Loops
StepsDefine a recursive function.Define a base case for that function that the number should be greater than zero.If the number is greater than 0, call the function again with the argument as the number minus 1.Print the number.Enter the upper limit: 512345Enter the upper limit: 1512..15Examplepackage main import ( "fmt" ) func printNo(number int){ if number >= 1{ printNo(number-1) fmt.Println(number) } } func main(){ var upper int fmt.Print("Enter the upper limit: ") fmt.Scanf("%d", &upper) printNo(upper) }OutputEnter the upper limit: 5 1 2 3 4 5

When it is required to demonstrate a counter and dictionary intersection, the Counter and dictionary can be used.Below is the demonstration of the same −Examplefrom collections import Counter def make_string(str_1, str_2): dict_one = Counter(str_1) dict_two = Counter(str_2) result = dict_one & dict_two return result == dict_one string_1 = 'Hi Mark' string_2 = 'how are yoU' print("The first string is :") print(string_1) print("The second string is :") print(string_2) if (make_string(string_1, string_2)==True): print("It is possible") else: print("It is not possible")OutputThe first string is : Hi Mark The second string is : how are ...
Read MoreGolang Program to Determine Recursively Whether a Given Number is Even or Odd
StepsTake a number from the user and store it in a variable.Pass the number as an argument to a recursive function.Define the base condition as the number to be lesser than 2.Otherwise, call the function recursively with the number minus 2.Then, return the result and check if the number is even or odd.Print the final result.Enter a number: 124Number is even!Enter a number: 567Number is odd!Examplepackage main import ( "fmt" ) func check(n int) bool{ if n < 2 { return n % 2 == 0 } return check(n - 2) } func ...
