PAYING - Paying in Byteland |
There are infinitely many coin denominations in the Byteland. They have values of 2i for i=0, 1, 2 ... . We will say that set of coins c1, c2 ... ck is perfect when it is possible to pay every amount of money between 0 and c1 + ... + ck using some of them (so {4, 2, 2, 1} is perfect while {8, 1} is not). The question is - is it always possible to change given sum n into a perfect set of coins? Of course it is possible ;). Your task will be more complicated: for a sum n you should find minimal number of coins in its perfect representation.
Input
First line of input contains one integer c ≤ 50 - number of test cases. Then c lines follow, each of them consisting of exactly one integer n ≤ 101000.
Output
For each test case output minimal number of coins.
Example
Input: 5 507 29 8574 233 149 Output: 14 7 21 11 10

@Adit Goel {1,1,1,2,3,4,7,15,31,63,126,253} is not a valid solution for 507 because 3, 7, 15, 31, 63, 126, and 253 are not valid coin denominations; this can be inferred from the problem statement. |

why is the answer for 507->14 {1,1,1,2,3,4,7,15,31,63,126,253} makes all possible sums |

Any problem that anyone might be facing, if the test cases are working fine, has to do with large numbers. |

is limit of n actually 10^1000. will we have to store the number in strings? |

To get the all values <=29 : I can take the coins of 1,2,4,8,16 and make all possible sum. Why the answer is 7 for this test case ? Please read the problem statement carefully .. the sum of the values of the coins you're using must be equal to 29 ! Last edit: 2011-11-16 09:01:00 |
