You are given two ropes with different lengths. However if you set both ropes of fire from the tip, they will both burn at exactly one hour.
You are asked to measure 45 minutes using just these two ropes and you and NOT allowed to cut the ropes at all.
How will you do this?
1. Burn one of the ropes from both ends. The rope will burn completely at half time (i.e. 30 minutes).
2. Also burn the other rope from one end at the same time. At the time rope #1 completely burns, rope #2 will be half length. That is, it now has 30 minutes left to burn.
3. Immediately set the other side of rope #2 on fire too. It will burn at half the time left (i.e. 15 minutes).
4. Let rope #2 burn completely too.
You have successfully measured 30minutes + 15 minutes = 45 minutes.

The messaging service and social-media platform owes creditors roughly $700 million by the end of April, according to people briefed on the company’s plans and loan documents viewed by The Wall Street Journal. At the same time, Telegram Group Inc. must cover rising equipment and bandwidth expenses because of its rapid growth, despite going years without attempting to generate revenue.
What is Telegram?
Telegram’s stand out feature is its encryption scheme that keeps messages and media secure in transit. The scheme is known as MTProto and is based on 256-bit AES encryption, RSA encryption, and Diffie-Hellman key exchange. The result of this complicated and technical-sounding jargon? A messaging service that claims to keep your data safe.Why do we say claims? When dealing with security, you always want to leave room for scrutiny, and a few cryptography experts have criticized the system. Overall, any level of encryption is better than none, but a level of discretion should always be observed with any online connected system, even Telegram.
