Hn to apne bole ki hamare (HI) ke case me H aur I same column ya same column me nahi hey so encryption rule me dekhe to
for H : H ka row aur I ka column jaha intersect hoga wahi hamara H ka CipherText hoga = B
for I : I ka row aur H ka column jaha intersect karenge wahi I ka CipherText hoga = M
but apne uske baad decryption ke case me bole ki iska ulta process hoga par ye reverse rule na sirf isi case me apply nahi hoga
Same row and same column me koi 2 letter pair nahi hey to uska encryption and decryption ka process same he hoga aap try kar sakte hey.
par apne ulta information dediya ki encryption me row and column intersection hoga aur decryption me column and row intersection hoga so app check recheck kijiye please.

[@SHASHANKSHEKHARANS]

What if the plain text has an odd number of letters, how to group them in a pair of two. In the given example as 'e' was repeated in 'tree' so you introduced x which made the total number of characters/letters of the plain text = 26 that is even. Can you explain the case of total number of odd letters with no repetations?

[@CSEconceptswithParinita]

Shashank, if the plain text has odd number of letters, you've to pair the last remaining letter with a dummy character 'x'

[@SHASHANKSHEKHARANS]

@@CSEconceptswithParinita was it 'x' or 'z' ?
And also just to confirm, if we have a word with two consecutive 'xx' we insert 'z' in between. Right ?

[@CSEconceptswithParinita]

@@SHASHANKSHEKHARANS yes, that's right. And when we've odd number of characters, we normally append 'x' at the end.
