Corona2020 (Editorial)

Check all possible operations between the numbers $a, b$ , and $c$ . If the value of the resulting expression equals $2020$ , print this expression. Otherwise, print the word CORONA.

Algorithm implementation

Read the input data.

scanf("%d %d %d", &a, &b, &c);

Iterate over all possible operations between the numbers. Depending on the result, print the appropriate answer.

if (a + b + c == 2020) printf("%d+%d+%d", a, b, c); else
if (a + b - c == 2020) printf("%d+%d-%d", a, b, c); else
if (a - b + c == 2020) printf("%d-%d+%d", a, b, c); else
if (a - b - c == 2020) printf("%d-%d-%d", a, b, c); else
                       printf("CORONA\n");

Python implementation

Read the input data.

a, b, c = map(int, input().split())

Iterate over all possible operations between the numbers. Depending on the result, print the appropriate answer.

if a + b + c == 2020:
  print(f"{a}+{b}+{c}")
elif a + b - c == 2020:
  print(f"{a}+{b}-{c}")
elif a - b + c == 2020:
  print(f"{a}-{b}+{c}")
elif a - b - c == 2020:
  print(f"{a}-{b}-{c}")
else:
  print("CORONA")
