Use C programming and Psuedo code, thanks!

1. Create a script with if, else if, and else conditionals to calculate the Total Resistance (RT) 1) r1, r2, and r3 are connected in series manner. (R T-rl+r2+r3) 2) rl, r2, and r3 are connected in parallel manner.(R T 1/(1/r1)+(1/r2)1/r3)) 3) r is connected to the parallelly connected r2 and r3 in series manner. (Let's call this Combination) (R T-r1+ r2xr3/(r2+r3)) The output should be What is the resistance of R1? [You type in the value] What is the resistance of R2? [You type in the value What is the resistance of R3? You type in the value] What kind of combination result are you looking for?[You type in S, P, or C The Total Resistance is [your result] ohms since r1, r2, r3 are connected in [series, parallel, combination] manner. Test the result with r1-10 . r2+ 20 , and r3-30
