Bonsoir,
Explications étape par étape
f(1)=2
f(2)=f(f(1))=3
f(f(f(1))=5
A la 582ème itération,
f(777)=390
f(390)=779
DIM a AS LONG, b AS LONG, c AS LONG, x AS LONG, i AS LONG
a = 1
b = 2
c = 3
i = 0
DO WHILE a <> 777
IF a MOD 2 = 0 THEN
x = a + 2
ELSE
x = a + 4
END IF
i = i + 1
PRINT i, x
a = b
b = c
c = x
LOOP
PRINT "a="; a
PRINT "b="; b
PRINT "c="; c
PRINT "x="; x
PRINT "i="; i
END
