int main()

    int i,key=0,n;
    scanf("%d",&n);
    int list[n];
    for(i=0;i<n;i++){

        if(list[i]>=list[i+1]){

What is wrong with my code???

23 
Scanner inpu=new Scanner(System.in);
        int N;
        int count=0;
        N=inpu.nextInt();
        int array[]=new int[N];
        for (int i = 0; i <N; i++) {
            array[i]=inpu.nextInt();
        }
        for (int i = 0; i <N-1; i++) {
               if(array[i]<=array[i+1]){
                   count++;
               }
        }
        if(count==N-1){
            System.out.print("yes");
        }else{
            System.out.print("No");
        }

whats the prblm in my code ?

It seems that you have solved the problem yourself.

25

whats the problem in this code ?

26

You wrote yes instead of Yes

27

What about 1? What if the line is 1…how do i check if this is asscending or not?

28 
#include<iostream>
using namespace std;
main()
{
  int i,n;
  cin>>n;
  int a [n];
  for(i=1;i<n;i++)
  {
    if(a[i]>a[i-1])
    {
      cout<<"No";
      return 0;
    }
  }
  cout<<"Yes";
}

What is the problem in my code?

Sorry, it’s my bad. Now i am able to figure it out :grinning_face_with_smiling_eyes:

33
code 
#Python 3.8

N = int(input())
A = input().split()

def ascend(lis):
	index = 0
	outdex = len(lis)
	while index < outdex-1:
		if lis[index] > lis[index+1]:
			return False
		index += 1
	return True

if ascend(A):
	print("Yes")
else:
	print("No")

why the code shows wrong answer on 5th case?

@Marzuq01 This is happening because you are comparing the numbers as strings instead of integers.

In Python:

>>> 9 > 10
False
>>> '9' > '10'
True

Change your second line from A = input().split() to A = map(int, input().split()).

36

N = int(input())
A = input()
list = A.split(" “)
while len(list)!=N:
A = input()
list = A.split(” “)
Asd = True
for i in range(N):
if i+1<N:
if list[i]>list[i+1]:
Asd = False
if Asd:
print(“Yes”)
else:
print(“No”)
N = int(input())
A = input()
list = A.split(” “)
while len(list)!=N:
A = input()
list = A.split(” ")
Asd = True
for i in range(N):
if i+1<N:
if list[i]>list[i+1]:
Asd = False
if Asd:
print(“Yes”)
else:
print(“No”)

Whats is wrong here?
Am getting error on test 5.

Here is a solution in c++

#include<iostream>
using namespace std;

int main(){
    int times;
    cin>>times;
    int min =-3;
    int right = false;
    for(int i=0; i<times; i++){
        int number;
        cin >> number;
        if(number> min){
            min = number;
            right = true;
        }
        else if(number == min){
            right = true;
        }
        else{
            right = false;
            break;
        }
    }
    if(right==true){
        cout<<"Yes";
    }
    else{
        cout<<"No";
    }
}
