Where is it going wrong (chewbacca number)

#1

mujhe question thik se samaj nhi aaya lekin itna samaj aaya h ki least number output krana h saari digits m se aur number se pehle zero nhi hona chahiye

isi ke according program h

#2

basically you have to invert the digits to make it smaller but no leading zeroes
for ip 999 ur op 999 but ans 900 check it @anujsharmabadboy

#3

@vatsal38
lekin aise sample input 4545 h par uska output toh 4444 h

#4

@anujsharmabadboy yes

#5

if at first place its 9 then u have to take care

#6

samaj nhi aaya bhai
kuch example dekar samjhao na

#7

for every digit if its greater than equal to 5 you have to do 9-digit .
only corner case if first digit 9 like 954 u cant make it 044 as it contains leading zeroes so ans is 944

examples
999 900
957 942
454 444
1234 1234
9021 9021
7777 2222

acha agar digit greater than 5 h toh 9 - digit (except for digit 9 itself)
aur digit less tha 5 ha toh leave as it is ??
asia hi h

#10

yup and 9 agar first place pe hai tohi usse nahi lena
909 ans is 900

#11

hmmm
lekin yeh jo barrier h 5 yeh question m kaha given h
apko kese pta chala ??

#12

logically socho 9-t given a question mein and minimum banana hai
so agar 4 hai toh 9-4=5 badha hai toh isse invert karne ka koi fayda nah ab agar t=5 hai toh 9-5=4 which is less. aise sochai

#13

okay bhai
ho gya submit
