1. Given a list L of digits from 1 to 9 and a number x, we would like to find out whether it is possible to insert some + symbols between some of the digits in L so that we get an expression that evaluates to x. For example, let L be 4637" and x be 56. In this case, it is possible to insert two + symbols to L and get "46+3+7, and the sum expression has value 56. Another example, let L be 1537" and x be 52. This case is also possible, since we can insert one + and get 15+37", which has value 52 after computation. But, if L is 14135" and x is 5000, then such insertion is impossible. (Note that you cannot change the order of the digits in L). Your task: Let L be 26357" and x be 3753, find out whether an insertion scheme as described above is possible. You should list all possible ways to insert "+ symbols into L
