You are given two integers N and K. Determine the Nth smallest integer with K set bits in its binary representation. Since the answer may be very large print the answer modulo 10e9+7.\n\nNotes:\n\u2022 A bit at a particular position in the binary representation of an integer is said to be set if its value is 1.\n\u2022 The integer N can be very large so it has been provided as a string in the input.\n\nExample:\n\nAssumptions:\n\u2022 N = 4\n\u2022 K = 2\nApproach:\nThe numbers with 2 set bits are 3, 5, 6, 9, 12.\nTherefore the 4th smallest integer with 2 set bits is 9.\n\nFunction description:\nComplete the solve function provided in the editor. This function takes the following 2 parameters and returns the Nth smallest integer with K set bits modulo 10e9+ 7:\n\nN: Represents a string denoting the integer N\nK: Represents an integer denoting the required number of set bits\n\n1<=K<=60\n1<=N<=10^(K+1)
