I have two lists of Person objects. I need to compare the lists to determine if items in list1 exist in list2 and vice versa. This is not a straight equals() scenario as the objects are not the same, but may have identical field values. It is those values that I need to compare. Currently, I am...

Write a program in java to input a word and display all the new words that can be formed by shuffling the letters in the word.

NICK binary thresholding essentially boils down to a convolution where the kernel at each pixel calculates the sum and squared sum (for the standard deviation). These values are then used in the threshold function to determine whether the grayscale value should be black or white. A kernel size o...

I am new to python and I am trying to define a formula to determine price paths for a stock using GBM. The problem is that when i hard code the inputs the loop is running fine.However, when I use the same code as a part of formula it's not looping beyond row-2. Please help: def gbm (S,r,sigma,T,...

I have written a class to quantize values to arbitrary bit depths within a specified amplitude. It is meant to process one value at a time, and has two ways of quantizing values. I wrote the class so that i could create objects of it as a property for another class, so that the quantization proc...
