Suppose you attend a party. To be sociable, you will shake hands with everyone else. Write the algorithm that will compute the total number of handshakes that occur. (Hint: Upon arrival, each person shakes hands with everyone who is already there. Use the loop to find the total number of handshakes as each person arrives.)

Ihave a singular monitor that is a tv for my computer. recently, i took apart my computer and put it back together. when i put in the hdmi cord and booted the computer to see if it worked, the computer turned on fine but the screen was blue with "hdmi no signal." i've tried everything that doesn't require buying spare parts, any answer is appreciated!
