Day 093

Kun masalalari:

🟢 2367. Number of Arithmetic Triplets
🟡 1630. Arithmetic Subarrays

O’qish uchun material:

*nix dagi quyidagi komanda bilan man <command> orqali tanishing:

- mkfifo

DIY:

*nix systemasda quyidagi komandalarni ketma-ket bajarib ko’ring. Buning uchun sizga 2 ta terminal kerak bo’ladi. 1-terminalda sender.sh fayl yasab, unga quyidagi scriptni yozamiz:

#!/bin/bash

mkfifo /tmp/sender_pipe

while true; do
read -p "Enter a message to send: " message
echo "$message" > /tmp/sender_pipe
done


2-terminalda esa receiver.sh fayl yasab, quyidagi scriptni yozamiz:

#!/bin/bash

while true; do
message=$(cat < /tmp/sender_pipe)
echo "Received message: $message"
done


Ikkala faylni “executable” faylga o’zgartiramiz (chmod +x <file_name>). Va 2 ta terminalda ishlatib ko’ramiz.
