Program to Find sum of series 1+(1+3)+(1+3+5)+....+N

Problem statement:- Program to Find the sum of series 1+(1+3)+(1+3+5)+....+N.

Example:    

                Input: n=5

                Output: The sum of the series = 14 /* sum series =                                                                                1+(1+3)+(1+3+5)=1+4+9=14*/

              

                Input: n=8

                Output: The sum of the series = 30 /* sum series =                                                                                1+(1+3)+(1+3+5)+(1+3+5+7)=1+4+9+16=30*/
