nr
Se generează un şir de numere naturale ai cărui primi termeni sunt, în această ordine:
1, 20, 21, 300, 301, 320, 321, 4000, 4001, 4020, 4021, 4300, 4301, 4320, 4321, 50000,...
Dându-se numerele naturale k
, n
și x
, să se determine: a) numărul de termeni ai şirului care au prima cifră (cea mai semnificativă) egală cu k
; b) cel de-al n
-lea termen al şirului din enunţ; c) cel mai mare termen al şirului, mai mic sau egal decât x
.
