![]() We do this until we have explored all the elements, and size of the unknown partition shrinks to zero. Now, we explore the array with the help of low pointer, shrinking the unknown partition, and moving elements to their correct partition in the process. (2) To move the right side of the browser window to the left Alt+Spacebar then press the S key once to start the move, then the right arrow once to select the right side, then the left arrow many times until you see the window border come to the part of the screen where you want it, then press Enter to finish Good thing they invented the mouse. We will divide the array into three partitions with the help of two pointers, low and high. The first color will be for all negative integers and the second color will be for all positive integers. Here, we will use the famous Dutch National Flag Algorithm for two “colors”. (Create an error right at the start of the file if you have to.) If stumped, try the general tricks. If you like GeeksforGeeks and would like to contribute, you can also write an article using or mail your article to See your article appearing on the GeeksforGeek’s main page and help other Geeks. Please refer to Rearrange positive and negative numbers with constant extra space for details. The problem becomes difficult if we need to maintain the order of elements. This is an in-place rearranging algorithm for arranging the positive and negative numbers where the order of elements is not maintained.
