How to fix/solve Presentation Error

What is “Presentation Error”?

As you start participating in coding competitions, you are fully acknowledged with most of the errors which generally occurs during the program. What to do if you’re facing an error that doesn’t usually occurs i.e., a special type of error known as “Presentation Error”.

These errors may occurs due to the following factors:

1) If there is wrong formatting from your side, the answer seems to be correct but the online judge doesn’t identifies it.

2) If an output results to an integer but you’re presenting it in the form of string, then it may be a serious issue.

For e.g., the program OUTPUT should be 15.76

ASSUME THAT WE HAVE THE FOLLOWING JAVA CODE SNIPPET:

String ans="15.76";

System.out.println(ans); //gives a presentation error

float correct_form=Float.valueOf(ans);

System.out.printf("%.2f",correct_form); // no presentation error

Remember the saying:

“Giving a CLUE is meaningless until it is definite.”

Hope this articles helps you a lot, but if the problem persists, then comment below for further solutions.

How to fix/solve Compilation Error in Python

A Quick Overview on Compilation Error A Compilation Error is a special type of error that occurs while using Python as Source Code. The main reason behind this error is that python is an interpreted language. So, the online judge rather than interpreting it compiles the code and hence the error occurs. The best approach to tackle these kind of problems is either use a compilation command or convert the program in single line using the single function containing the whole program For.e.g., Program to convert a character in LowerCase at a specified place. def mains(): //Driver Function n,K=input().split() n=int(n) K=int(K) S=input() print(S[:(K-1)]+chr(ord(S[K-1])+32)+S[(K):]) mains() Input: 4 3 TEAM Output: TEaM Hope this articles ...

A feature phone is a mobile phone that retains the form factor of earlier-generation phones, with button-based input and a small display. Feature phones are sometimes called dumbphones in contrast with touch-input smartphones . [1] They tend to use an embedded operating system with a small and simple graphical user interface , unlike large and complex general-purpose mobile operating systems like Android or iOS . Feature phones typically provide voice calling and text messaging functionality as well as basic multimedia and Internet capabilities and other services offered by the user's wireless service provider . Feature phones have a backlit LCD screen, a hardware notification LED , and micro USB port and have a physical keyboard, a microphone, SD card slot, a rear-facing camera to...
