Answer to cassidoo interview question for 4.9.2018

ArrayDeletion.py

# Given an unsorted array arr and a number n, 
# delete all numbers in arr that are greater than n.

arr = [3,4,6,1,8,2,6,7,10]
num = 7

def deleteElements(arr, num):
	for x in arr:
		if x > num:
			arr.remove(x)
	return arr

print deleteElements(arr, num)

#  Alternative way that generates a new list without altering original
newArr = list(filter(lambda x : x <= num, arr))
print newArr
