The bindec() function convert a binary number to decimal number.Syntaxbindec(bin_str)Parametersbin_str − The binary string to convertReturnThe bindec() function returns decimal value of the specified string bin_strExample Live DemoOutputThe output displays that the bindec() function returns a decimal value:13
The dechex() function converts decimal to hexadecimal. It Returns the hexadecimal string of the specified decimal.Syntaxdechex(num)Parametersnum − The decimal value to be convertedReturnThe dechex() function Returns the hexadecimal string of the specified decimal.Example Live DemoOutputf7c6
Given a string, our task is to check weather this string is palindrome or not.AlgorithmStep1: Enter string as an input. Step2: Using string slicing we reverse the string and compare it back to the original string. Step3: Then display the result.Example codemy_string=input("Enter string:") if(my_string==my_string[::-1]): print("The string is a palindrome") else: print("The string isn't a palindrome")OutputEnter string:madam The string is a palindrome Enter string:python The string isn't a palindrome
The abs() function returns the absolute value of a number.Syntaxabs(num)Parametersnum − The number for which we want to get the absolute value. If the num is float, then the return type will be float, otherwise it is an integer.ReturnThe abs() function returns the absolute value of the specified number.Example Live DemoOutput3.19.7Let us see another example −Example Live DemoOutput2050
The acos() function returns the arc cosine of a number. It specifies a number in the range -1 to 1. Returns NaN, if num is not in the range -1 to 1.Syntaxacos(num)Parametersnum − The number for which you want to return the arc cosine. A number in range -1 to 1.ReturnThe acos() function returns the arc cosine of the specified number.Returns NaN, if number is not in the range -1 to 1.Example Live DemoOutput1.04719755119662.6905658417935Let us see another example −Example Live DemoOutput1.570796326794903.1415926535898NAN
One of the methods in the Timer class is the void schedule(Timertask task, long delay) method. This method schedules the specified task for execution after the specified delay.Declaration −The java.util.Timer.schedule(Timertask task, long delay) is declared as follows −public void schedule(Timertask task, long delay)There are few exceptions thrown by the schedule(Timertask task, long delay) method. They are as follows −IllegalArgumentExceptionThis exception is thrown if delay is negative, or delay + System.currentTimeMillis() is negative.IllegalStateExceptionThis exception is thrown if task was scheduled or cancelled beforehand, timer was cancelled, or timer thread terminated.NullPointerExceptionThis exception is thrown if the task is null.Let us see a ...

Reference variableReference variable is an alternate name of already existed variable. It cannot be changed to refer another variable and should be initialized at the time of declaration. It cannot be NULL. The operator ‘&’ is used to declare a reference variable.The following is the syntax of reference variable.datatype variable_name; // variable declaration datatype& refer_var = variable_name; // reference variableHere, datatype − The datatype of variable like int, char, float etc.variable_name − This is the name of variable given by user.refer_var − The name of reference variable.The following is an example of reference variable.Example Live Demo#include using namespace std; int ...
