Reverse the number by different approaches in many programming languages(that I know)

reversing_number

Reverse the number by different approach

Old approach:

Modulo and integer divide to get the number

Advantage:

• Simple, arithmetic operation required

Disadvantage:

• Dealing with long number seems to be very hard to achieve

New approach:

Using built-in function:

Convert number to string and use built-in function to reverse the string then return

Advantage:

• Dealing with big number is a piece of cake

Disadvantage:

• Some programming language doesn't have built-in reverse string function
• Require some simple knowledge when dealing with string

Handmade reverse function:

Instead of using built-in function, we implement our own reverse function

Advantage:

• Like using built-in function

Disadvantage:

• Dealing string in some low-level programming language may require strong basic CS knowledge
