Pseudocode for how to polish your shoes: ` Pseudocode: PolishShoes 1. Start 2. Gather materials: shoes, shoe polish, brush, soft cloth. 3. Clean shoes: Use the soft cloth to wipe off any dirt or dust from the shoes. 4. Apply polish: Take a small amount of shoe polish with the brush and apply it evenly over the entire surface of the shoes. 5. Let dry: Allow the polish to dry for a few minutes. 6. Buff: Using a clean section of the soft cloth, rub the shoes vigorously until they achieve a desired shine. 7. End ` 4. Algorithm to input three sides of a triangle and print if it is scalene, isosceles or equilateral: ` Algorithm: ClassifyTriangle 1. Start 2. Read side A, side B, side C 3. If (A + B > C) AND (A + C > B) AND (B + C > A) Then 4. If (A = B) AND (B = C) Then 5. Print "Equilateral Triangle" 6. Else If (A = B) OR (B = C) OR (A = C) Then 7. Print "Isosceles Triangle" 8.
