We have n people in a room, where n is an integer greater than or equal to 1. each person shakes hands once with every other person. what is the total number, h(n) , of handshakes? write a recursive function to solve this problem. to get you started, if there are only one or two people in the room, then handshake(1) = 0 handshake(2) = 1 if a third person enters the room, he or she must shake hands with each of the two people already there. this is two handshakes in addition to the number of handshakes that would be made in a room of two people, or a total of three handshakes. if a fourth person enters the room, he or she must shake hands with each of the three people already there. this is three handshakes in addition to the number of handshakes that would be made in a room of three people, or six handshakes. if you can generalize this to n handshakes, you should be able to write the recursive solution.

Hey i just logged on and one of the moderators deleted a bunch of my answers to questions, even though the answers were right and the people it doesn't make sense but if anyone wants to talk about anything just message me lol (this is super random lol)

Formatting rows and columns is similar to cell formatting. in an openoffice calc spreadsheet, you can format data entered into rows and columns with the of the rows and columns options. you can insert rows and columns into, or delete rows and columns from, a spreadsheet. use the insert or delete rows and columns option on the insert tab. alternatively, select the row or column where you want new rows or columns to appear, right-click, and select insert only row or only column options. you can hide or show rows and columns in a spreadsheet. use the hide or show option on the format tab. for example, to hide a row, first select the row, then choose the insert tab, then select the row option, and then select hide. alternatively, you can select the row or columns, right-click, and select the hide or show option. you can adjust the height of rows and width of columns. select row and then select the height option on the format tab. similarly, select column, then select the width option on the format tab. alternatively, you can hold the mouse on the row and column divider, and drag the double arrow to the position. you can also use the autofit option on the table tab to resize rows and columns.
