Cows & Chickens in Python
Cows & Chickens: There are 63 animals in a farm which has only chickens and cows. Leg count is 206. Given that chickens have 2 legs and cows have 4, write a Python program to figure out the number of chickens and cows there are in the farm. Hint: A simple for loop should do the trick.
Cows & Chickens
totalNumberOfAnimals = 63
totalNumberOfLegs = 206
for numberOfChickens in range(totalNumberOfAnimals + 1):
numberOfCows = totalNumberOfAnimals - numberOfChickens
if 2 * numberOfChickens + 4 * numberOfCows == totalNumberOfLegs:
print("Number of Chickens: {}".format(numberOfChickens))
print("Number of Cows: {}".format(numberOfCows))
