I think i got got bit more simpler solnn with lesser steps

1. Fill 5 ltr jar, pour it intoo 3 ltr till its full
2. Now 3 ltr jar is full n 5 ltr jar has 3 ltrs in it.
3. Empty 3 ltr jar, and pour 2 ltr in 3 ltr jar,, now 4 ltr has 3 ltrs in it and 5 ltr jar is empty
4. Fill 5 ltr jar and out of the 5ltr jar shift water in 3 ltr jar, since only 1 ltr can be tranferred into 3 ltr jar,,
the 5 ltr jar has 4 ltr water in it..
