@Ashu1318
for 899 its giving 1
for 900 its giving tle
check it
use string to store no then simply iterate from second index to last and if req s[i]=9-s[i]
also check for first letter separately

#3

can’t we some modification in this code also???

#4

@Ashu1318 yes we can but it would become complex and complicated also no can be large so its better to use a string
using string its just 3 to 4 line code
