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!Example Live Demopackage main import (    "fmt" ) func check(n int) bool{    if n < 2 {       return n % 2 == 0    }    return check(n - 2) } ...

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..15Example Live Demopackage 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

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 ...

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!Example Live Demopackage 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

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!Example Live Demopackage main import "fmt" func main(){    var n int    fmt.Print("Enter any number: ")    fmt.Scanf("%d", &n)    sum1 := 0    for i:=1; ...
