In our previous blog we have learnt about
Today let’s deal with Integer reversal,
“Given an integer, return an integer that is the reverse ordering numbers ie, revese(-51) = -15, reverse(-90) = -9, reverse(80) = 8”
Let’s quickly solve the question!!
In our previous blogs we understood how to reverse a string, here’s the same one but we are converting into string and string to array to reverse.
The little trick here is,
`parseInt(‘330-’)` will give the output 330, which means parseInt will take the first possible numbers, ie, parseInt('220-dskd') will give me 220.
And the second trick is Math.sign(200) will give 1 on passing negitive number we will get -1. Just to handle the sign we are using this method.
