I am writing a greedy algorithm (Python 3.x.x) for a 'jewel heist'. ceil (dr / nr) 9 ef. That is, each fraction in the expression has a numerator equal to 1 and a denominator that is a positive integer, and all the denominators differ from each other.The value of an expression of this type is a positive rational number a/b; for instance the Egyptian fraction above sums to 43/48. Also, in general it's not possible to recover the fraction that was used to generate the float since the float's limited precision essentially represents the actual rationals in lumps, like the pixels on a screen represent space in lumps. You can learn these from the linked chapters if you are not familiar with these. 1 def egyptianFraction (nr, dr): 2 print ("The Egyptian Fraction "+ 3 "Representation of {0} / {1} is". Hence, fraction of C (i.e. And the total profit is 100 + 280 + 120 * (10/20) = 380 + 60 = 440.
