Counting Equal Pairs with Tail Recursion
The cuentaIgualesTail function calculates the number of pairs in a list where the first element of the pair, when passed through a function f, is equal to the second element. It uses tail recursion for efficiency.
def cuentaIgualesTail(listaTuplas: List[(Int,Int)], f: (Int)=> Int) : Int = {
cuentaIgualesTailAux(listaTuplas,f,0)
};

Find-S Algorithm Implementation in Python
This section demonstrates the Find-S algorithm using the Pandas library in Python.
First Find-S Example
import pandas as pd
attributes = ['AirTemp', 'Temp', 'Humidity', 'Wind', 'Water', 'Forecast']
num_attributes = len(attributes)
filename = pd.read_csv('Weather.csv')
print(filename)
target = ['Yes', 'Yes', 'No', 'Yes']
print(target)
hypothesis = ['0'] * num_attributes
for i in range(len(target)):
if target[i] == 'Yes':
for j in range(num_attributes) Read More
