Write a c program which leads to time complexity equation as below :
a2^x + smaller terms

So, you are trying to solve for something, and the only way to do that is through applying the inverse of the given operation. this is because you are trying to "undo" everything and get your variable alone.

for example, if you have x+2=4, the only way to get x alone is to subtract 2, but you need to do this to both sides because you want the same equation as when you started. you are just trying to shift everything away from your variable

then the equation will be   x+2-2=4-2 which means x=2
plug it back in to check, 2+2=4, this is correct so you know you have done it right.'

however, if you hadnt done this to both sides watch what happens

x+2-2=4 which means x=4, now check your answer

you would get 4+2=4 which means 6=4 and you know that is  not true

My favorite is "be concise."have you ever received an email and had to read a page full of information? by the time you finished reading it, you had to re-read it? i have even hit "reply" so that i could break it down into separate paragraphs and send it back to myself.what is concise? get to the point, fast. when opening an email like this, some will close it or print it to read later.i learned to use the subject line to prepare the reader for content. such as, "need on (blank), " "info only re: (blank)," "request input on (blank)," "read before (blank) meeting." these are just some.if you are asking for something, make that your first sentence. follow this by who, what, when, where, and how. use these, as necessary. example; (1) who (who needs it and or who does it), (2) what (specific description of what is needed), (3) when (specific, i need this by 8: 00 am monday or i need this by 10: 00 am today), (4) where (does it have to be printed and taken to someone, maybe the place of the meeting), (5) how (i need it scanned or faxed back to me at this email address, provide me with a hard copy).do not send yet. re-read it. did some spell check change a word? maybe let someone else read it for understanding. you want to avoid multiple emails asking for clarification. if important, put a read receipt on it. you will know it was opened, not necessarily read.end with a you.
