The bits of an integer number can be reversed to obtain another number. An example of this is given as follows −Number = 11 Binary representation = 1011 Reversed binary representation = 1101 Reversed number = 13A program that demonstrates this is given as follows −Example Live Demopublic class Example {    public static void main(String[] args) {       int num = 14;       int n = num;       int rev = 0;       while (num > 0) {          rev = 1;       }       ...

The length of the longest consecutive 1’s in the binary representation of a given integer involves the length of the longest series of 1’s that occur together. An example of this is given as follows −Number = 13 Binary representation = 1101The length of the longest consecutive 1’s in binary representation of 13 = 2A program that demonstrates this is given as follows −Example Live Demopublic class Example {    public static void main(String strings[]) {       int num = 55;       int n = num;       int count = 0;       while (num!=0) {          num = (num & (num
