write a program to find the area under the curve y=f(x) between x=a and x=b integrate y=f(x) between the limits of a and b

Yes. "Memory pools" are useful in many situations. The bad news is that I'll need to drag you through the mire of how it acts before we talk about all the uses. Firstly, recall
A string S is said to be "Super ASCII", if it contains the character frequency equal to their ascii values. String will contain only lower case alphabets (''a''-''z'') and the asci
