Problem explained with concepts and code
Explanation of Reverse Integer Problem
Problem says : I will give you a 32- bit signed integer , all you have to do is just reversing it with some conditions . Before that ,let’s see what is 32-bit signed integer , its a range of numbers between [−231, 231 − 1] as mentioned in the problem . And if input excluded that range then return 0 .
Now see the examples : In first example problem simply says to reverse and and in second they don’t want to move the negative sign and in third they just ignored the zero by removing it .
Concepts in Problem
Abs() : The abs() function is used to return the absolute value of a number . for more.
Strip() : Use str. strip() to remove leading and trailing zeros .
Slicing : Accessing parts of segments is called slicing.
Solving Reverse Integer Problem
Let’s us code this problem in Python
In line 3 we are making a variable as containing a absolute string value of x which is main input . and in next line we striped the zeros from leading and training end . In line 5 we reverse the y string and condition we check for range of 32 bit and if the condition become false then we return 0 as in problem says . And further we check for conditions and return the values .
