Factorial na "onwa": otú gbakọọ. ihe atụ nke mmemme

Education mmemme bụ ụzọ si mfe mgbagwoju. Ebe mụtachara data ụdị na rụọ nke asụsụ, gaa cyclic owuwu. Ebumnobi maka cycles e nwere imerime: site na mmepụta nke nọmba a kọlụm na ngụkọta oge nke ichekwa mgbagwoju anya formulas. O sina dị, malite programmers ajụjụ: "Olee otú gbakọọ factorial ke" onwa "?"

Mejuputa a nsogbu nwere ike dịkarịa ala n'ụzọ atọ. Ha na-eji dị iche iche rụọ.

mgbakọ na mwepụ ozi

Tupu etinyewe na ndị na-ewu, ọ dị mkpa na-amụ ozizi algọridim na ide ihe. Na nzuógügü, na factorial bụ ngwaahịa nke a ọnụ ọgụgụ nke na inwale okwu na nti integers erughị ya.

Ghọta definition nke ihe atụ ga-enyere. Ka e were ya na ị chọrọ ịhụ ndị factorial nke nọmba 3. The mkpebi nke 3! = 3 2 * 1 = 6.

Ọ na-egosi ihe emereme mkpu akara, nke na-etinye mgbe nọmba. Mkpa Note: The factorial a kọwara naanị maka nti integers. N'otu oge ahụ, ẹkenam echiche nke efu: 0! = 1.

Tụlee okwu aka maka nnukwu - a ogologo na-arụ. Na adị na ngụkọta oge usoro, iji kọmputa na mmemme. Ọzọ, tụlee ụzọ chọta factorial ke "onwa".

Mbụ usoro

The koodu n'okpuru na-egosi version nke usoro ihe omume.

Na atụ iji a ọtụtụ ndị mejupụtara na-ewu na ọnọdụ na e dere tupu loop ahu. ndekọ syntax:

mgbe {ọnọdụ} eme {} posledovatelnost_operatorov;

The koodu-agba dị ka ndị a: omume achọpụtazi ndaba nke okwu {ọnọdụ}, na ikpe nke a mma ule na-aga ka posledovatelnost_operatorov {}.

Iweghachi ka usoro ihe omume ahụ, i kwesịrị ntị ka ndị na-esonụ e:
