Golang 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 ...
