Sequence
Searching for a value
Core exercise
Write indiceDe(int[] tableau, int valeur) that returns the index of the first occurrence of valeur, or -1 if it is absent.
A workshop goes here: you write and run code in it. It requires JavaScript.
Starting code
Exercices.java
public class Exercices {
public static void main(String[] args) {
int[] t = { 4, 8, 15, 16, 23, 42 };
System.out.println("15 est a l'indice " + indiceDe(t, 15));
System.out.println("99 est a l'indice " + indiceDe(t, 99));
}
public static int indiceDe(int[] tableau, int valeur) {
// TODO
return -1;
}
}
The core exercise is validated in the workshop, which requires JavaScript.
Hint 1
Here the index matters: a classic for loop with i. Returning -1 for “absent” is a convention you will find again in indexOf.
