I can understand you brother . because i'm also facing the same difficulties . i always think i'm not good enough and my dream always be a dream no matter how hard i try .
but know what you never know what is written in future . i see this hard time as opportunity to create myself and learn from my previous mistakes .

As Will Smith said in movie "The Pursuit of Happyness"
"You got a dream... You gotta protect it. People can't do somethin' themselves, they wanna tell you you can't do it. If you want somethin', go get it. Period."

Attention!

Your solution 117241492 for the problem 1529C significantly coincides with solutions Shivam07sr/117233069, nayan007/117236570, X_VIDEOS123/117238246, shrutiagarwal_/117239198, Data_leak/117241492, mnityesh/117251336, An_K_Y/117251890. Such a coincidence is a clear rules violation. Note that unintentional leakage is also a violation. For example, do not use ideone.com with the default settings (public access to your code). If you have conclusive evidence that a coincidence has occurred due to the use of a common source published before the competition, write a comment to post about the round with all the details. More information can be found at http://codeforces.me/blog/entry/8790. Such violation of the rules may be the reason for blocking your account or other penalties. In case of repeated violations, your account may be blocked.
