String S is passed
as the input to the program. S may or may not have a single underscore embedded
in it. The program must reverse the String S till the first underscore and
print it as the output.
Input Format:
The first line contains S.
Output Format: The first line contains the
string S modified based on the given conditions.
Boundary Conditions: Length of S is from 3 to 100.
Example Input/Output 1:
Input:
abcd_pqrs
Output:
dcba_pqrs
Example Input/Output 2:
Input:
_kilo
Output:
_kilo
Example Input/Output 3:
Input:
nounderscore
nounderscore
Output:
erocsrednuon
Source Code:
import java.util.*;
public class Hello {
public static
void main(String[] args) {
Scanner
s=new Scanner(System.in);
String
s1=s.nextLine();
int

if(u==-1)
System.out.print(new StringBuffer(s1).reverse().toString());
else
if(u==0)

}

String[] s2=s1.split("_");
System.out.print(new

Source Code: //Python
s=input()
n=s.index("_")
if n==-1:
print(s[::-1])
elif n==len(s)-1:
print(s[:len(s)-1]+"_")
else:
print(s[:n][::-1]+s[n:])
this python code has some faults
ReplyDelete1.it returns a value error which has to be handled using a try except block
2.[::-1] missing in the print statement in the elif block
Else executes just fine!
bro can tell the code using try except block
DeleteThis python code has some error which if there is no underscore in the string thn how it will take it as in -1th index
ReplyDeleteSub string is not passesd as the input
ReplyDeleteI think this code fails to work for 3rd input ..since there is no "_" index() func will return with error.you may try it with a if and else instead. visit
ReplyDeletehttps://pythonic-solutions.blogspot.com/2020/09/reverse-string-till-special-character.html
for solution
x=input().strip()
ReplyDeletet=""
d=-1
d=x.find('_')
if d!=-1:
print(x[:d][::-1],end="")
print(x[d:])
else:
print(x[::-1])
#This code will pass all test cases💯
