Hello to all dear programmers on Codeforces! I am honored to say that on Yalda Night, which is a memorable and beloved night among Iranians, I was able to reach 1,000 solved problems. Two weeks ago, I set a goal for myself to reach this number of problems before winter, and fortunately, I succeeded. I can also say that this journey greatly contributed to my progress, and I am very happy about it.

As for Yalda Night, a night when we Iranians gather with each other and our families and enjoy being together, it is also one of our very old traditions. In the past, when night symbolized darkness and evil, from Yalda Night onwards, the nights start to get shorter and the days get longer, making this night a symbol of victory and new hope.

So, I wish all of you a happy Yalda Night and hope you have a wonderful evening with your families :)

Good night =D
