2014华为校园招聘试题答案(国外英文资料) 2014 HUAWEI campus recruitment exam questions and answers ======================================== 1 find the length of the last word in the string ******************************************************************* *hello *hello____word____ * ******************************************************************* #includestdio.h #includestring.h Void, main () { Char a[128]; Int b[128]; Int, m=0, n=0, len, I, j=0; Gets (a); Len=strlen (a); For (i=0; ilen; i++) { If (a[i]==) { B[j]=0; J++; } Else { B[j]=1; J++; } } For (j=0; jlen; j++) { If (b[j]==0) { N=0; } Else { N++; M=n; } } Printf (%d, m); } 2 a sequence of DNA consists of four letters of A/C/G/T. The ratio of G to C (defined as GC-Ratio) is the total number of occurrences of the two letters of the G and C in the sequence, divided by the total number of letters (that is, the length of the sequence). This proportion is very important in genetic engineering. Because high GC-Ratio may be the starting point of genes. Given a long DNA sequence and the minimum length required, researchers often need to find the highest subsequences in GC-Ratio. # include stdio.h # include string.h Void, main () { Char, a[256]={0}, b[256]={0}; Int, n=0, len=0, i=0, j=0, k=0, p=0, temp=0; Gets (a); Scanf (%d, n); Len=strlen (a); For (i=0; ilen-n+1; i++) { K=0; For (j=0; jn; j++) { If (a[i+j]==G||a[i+j]==C) { K++; } } If (tempk) { Temp=k; For (p=0; pn; p++) { B[p]=a[i+p]; } B[n]=\0; } } Printf (%s, B); } 3 output 7 numbers relating to numbers, including multiples of 7, and the number of 7 digits (such as 17, 27, 37, 70, 71, 72, 73,...) # include stdio.h Void, main () { Int, I, N, count=0; Int, a, B, C, D, e; Scanf (%d, n); Count=n/7; For (i=1; i=n; i++) { If (i%7==0) { ; } Else { E=i/10000; D= (i-e*10000) /1000; C= (i-e*10000-d*1000) /100; B= (i-e*10000-d*1000-c*100) /10; A= (i-e*10000-d*1000-c*100-b*10); If (7==a||7==b||7==c||7==d) { Count++; } } } Printf (%d, count); } 4 write a program that accepts a string with le
