Given a list of digits, find the fewest operations to make 100
A string of digits, which may or may not be in numerical order. The order of the digits cannot be changed, however plus (+) or minus (-) operators may be added between each so that the total sum is equal to 100.
The number of operators added, followed by the full sequence of digits and operators. The two can be separated by a space, tab, or new line sequence.
(There are ways of solving this with fewer operations)
