Problema
Return the largest of three integers. Practice comparisons with if statements; don't use a built-in max function.
Implement largest_of_three(a, b, c).
Input
a: The first number. b: The second number. c: The third number.
Output
Return the largest value.
Restricciones
-1,000,000,000 ≤ a, b, c ≤ 1,000,000,000
Ejemplos
Entrada:
a = 3
b = 9
c = 4
Salida esperada:
expected = 9Entrada:
long long a = 3;
long long b = 9;
long long c = 4;
Salida esperada:
long long expected = 9;Entrada:
long a = 3;
long b = 9;
long c = 4;
Salida esperada:
long expected = 9;Explicación
9 is greater than both 3 and 4.
Entrada:
a = -5
b = -2
c = -2
Salida esperada:
expected = -2Entrada:
long long a = -5;
long long b = -2;
long long c = -2;
Salida esperada:
long long expected = -2;Entrada:
long a = -5;
long b = -2;
long c = -2;
Salida esperada:
long expected = -2;Explicación
-2 appears twice and is the largest value.
Cómo abordarlo
Inténtalo primero por tu cuenta y luego abre las pistas una a una.
Pista 1
Compare the numbers pair by pair to identify the largest one.
Pista 2
A few conditional checks are enough; no search structure is needed.
Pista 3
Be careful with equal values, since ties should still return the correct largest number.
Complejidad esperada
O(1) time, O(1) extra space
