Pls check my code ...>>>> also What if the input number is zero " 0 " in the first step ?

Step 1 : var inputNum = parseInt( prompt("Please enter the bigger number"));

var randumNum = Math.floor ( Math.random () * inputNum) + 1 ;

alert("Result " + randumNum);

step 2 : var inputNum1 = parseInt( prompt("Please enter the bigger number")); var inputNum2 = parseInt( prompt("Please enter the smaller number"));

var randomNum = Math.floor(Math.random() * (inputNum1 - inputNum2 + 1) + inputNum2) ;

alert ("Result " + randomNum) ;

Your code performs similarly to the examples in the video.

In the first step, if the input number is 0 (or if it is 1), the output will always be 1.

Thank you for the reply . How should we avoid this and generate random number even if the input is 0 or 1.?

But the user is providing the limit for the range. An input of 0 or 1 limits the output to 1.

If you want to ignore the user's input, what range would you want to use?
