Using the digits 3, 4, 5, 6, 7, 8, and 9, how many 7-digit numbers can be constructed if the number must begin with an odd digit and digits may not be repeated? How many different sequences of nine decimal digits exists that have exactly ...
To find the number of 6-digit numbers that can be formed using the digit 2 two times and the digit 5 four times, we can follow these steps:Step 1: Identify the total number of digits We have a total of 6 digits, which consists
To find the number of 6-digit numbers that can be formed using the digits 1, 2, 3, 4, 5, and 6 exactly once, such that the number is divisible by its unit digit (with the restriction that the unit digit cannot be 1), we can follow these steps:<
We used a computer to exhaustively handle all the possible candidates formed by the subset of 304 脳 5074 = 1542496 combinations with Ai < 3003344 + 106 = 4003344. This revealed that a(6) = 3003344034004 is the smallest number in base 10 that cannot be collapsed using fewer than 6 plus ...

I am trying to find combinations of elements of a vector whose sum is greater or equal to a given value. For example: vec = [5 4 3 2 1]; criteria = 8.5; Then the output would look like [5 4] [5 3 2] [5 3 1] [4 3 2] ...
