Increasing Decreasing Sequence Problem Test Cases

#1

Hi, I am unable to solve for all test case, Please help me out https://ide.codingblocks.com/s/80305

#2

Check if your code is giving “True” as output for the below three conditions:

  1. Frst decreasing then increasing.
  2. Completely decreasing.
  3. Completely increasing.

If you it is still face problem… Then let me know

#3

hey,
In the same problem 2nd test case is showing wrong answer. i would be really glad if you could help.

#4

for(j=0;j<temp;j++){
if(a[j]<a[j+1]){
cout << “false”;
break;
}
}

i was wondering if this would ever execute? think.

and run your code for: 5 5 4 3 2 1
it will help you to figure out your mistake.
what should be the value of temp before third loop and what is it actually? think.

hopefully, this would help.

#5

Hi Sir, have checked the code for these three conditions it return true for all these test cases.

“First decreasing then increasing.”
“Completely decreasing.”
“Completely increasing.”

#6

now, check for this

5
5
4 //focus here
4 //
3
4

Hint: a strictly increasing or strictly decreasing function does not contain equal values.

solve this issue, and your code will pass all the test cases.

#7

the code return false for the 5 5 4 4 3 4

#8

unable to figure out where the actual issue lies, Please help

#9

@Shobhit-Sharma-1473370192798371 Check, again.
Your code is returning true for 5 5 4 4 3 4
I just executed it on this input and it is returning true

Sir, this is the url of my code “https://ide.codingblocks.com/s/80305” and this is the response that I am getting this reponse, I guess you might be referring to wrong url.

I hope this is not frustrating you that instead of sharing the correct code, I am just pointing out ur mistakes again and again.
But trust me, these learnings will help you in future.
Try to run it for:
5
1
2
3
2
1
The answer should be false

Suggestion:

  1. Next time, Run your code for all possible inputs.
  2. Understand the question and Try to think of all possible kind of inputs for your problem.

For this problem:

  1. decreasing then increasing : true
  2. Decreasing : true
  3. Increasing : true
  4. Single input (example: 1 5) : true
  5. Increasing then decreasing : false
  6. Same values at consecutive places : false
