Exo ton parakato kodika, pistevo oti tha nai efkolo poli, se kapoion na to
trexi me ena gcc apla...
To provlima einai oti stelno loipon, mia matrix[] array stin sinartisi
selsort(), mou sortari tin array, pame kala, stelno meta tin matrix[]
array sto freq_array() kai pragmati petixeno na perno, poses times ehei
vrei...OMOS. Exo kolisi sto pos telika na paro mia struct(?), array(?),
list(? den xero kai STL ), me tis metavlites kai tin sixnotita apla pou
emfanizontai...diladi mia nea isos matrix, pou na leei oti telika to 1 to
de 1 , to 2 to vrike 3, klp klp, kai oxi 1,1,2,2,2,3,3,4 klp klp...
Prospatho na vgalo mia routina pou apla na mou epistrefi tin sixnotita
emfaniseis ton apotelesmaton tis matrix....(Me para poli apla logia)
:-)
Efharisto!
