We are given an array of size ‘N’ and an integer ‘X’ where we have to find the number of subsets with the sum equal to ‘X’. If we carefully notice it is nothing but binary numbers from 0 to 15 which can be shown as below: Starting from right, 1 at ith position shows that the ith element of the set is present as 0 shows that the element is absent. Dataset operations can also be untyped, through various domain-specific-language (DSL) functions defined in: Dataset (this class), Column, and functions. We can use this to remove characters from a string. Using this method we produce a map …. Return 1; Declare an integer variable “ans” and initialize it with 0. The count parameter indicate the number of entries to be set in the resulting subset iterator. All the possible subsets for a string will be n (n+1)/2. If you know any better performing approach, please let our readers know by commenting here below. The getArray method is a standard JDBC method that returns the array elements as a java. The subset of a string is the character or the group of characters that are present inside the string. · L - the precision of the problem, .
