Electronic device usually require a personal code to operate. This particular device uses 4-digits code. Calculate how many codes are possible. Solution: Each code is represented by r=4 permutation with replacement of set of 10 digits{0,1,2,3,4,5,6,7,8,9} ...
In the above code, you can observe that this method is used to create permutations of the array elements. Permutations are being created based on the argument passed inside the method. N number of combinations can be made and that n can be the multiplication of length of Array instance multi...
