This article introduces you how to find the second largest number in an integer array, the content is very detailed, interested friends can refer to, I hope it can be helpful to you.

It may be in the form of a story: for example, how to find the second big diamond if the elevator stops from the first floor to the tenth floor

1 # include 2 # include 3 # define MINNUMBER-32768 4 int find_sec_max (int arr [], int size) 5 {6 assert (arr); 7 int maxnumber=arr [0]; 8 int sec_max=MINNUMBER; 9 int item0; 10 for (iTunes 1 int imaxnumber) 13 {14 sec_max=maxnumber; 15 maxnumber=arr [I] 16} 17 else 18 {19 if (arr [I] > sec_max) 20 sec_max= arr [I]; 21} 22} 23 return sec_max; 24} 25 int main () 26 {27 int arr [10] = {3 printf:% d\ n ", find_sec_max (arr,10)) 29 return 0; 30}

Determine whether a single linked list has a ring?

1 # include 2 struct LinkNode 3 {4 char val; 5 LinkNode* next; 6}; 7 bool check (const LinkNode* head) 8 {9 if (head==NULL) 10 return false; 11 LinkNode* low=head,*fast=head- > next; 12 while (fast&&fast- > next) 13 {14 low=low- > next; 15 fast=fast- > next- > next; 16 if (low==fast) 17 return true 18} 19 return false; 20}

Find the largest of the two numbers: there are two int variables An and B. do not use if,?: and switch or other judgment statements, find the largest of the two numbers.

Option 1:

Int max= ((aqb) + abs (aMub)) / 2

Option 2:

Int (int) * 8-1)

Write a function that returns the value of 1 "2" 3 "n (assuming that the result does not exceed the range of long integer variables)

Int sum (int n) {return ((long) 1qn) * ncord 2;} about how to find the second largest number in an array of integers is shared here. I hope the above content can be helpful to you and you can learn more. If you think the article is good, you can share it for more people to see.
