Mental health can affect daily living, relationships and physical health. Factors in people’s lives, interpersonal
connections and biological factors can all contribute to mental health disruptions. Looking after mental health
.fr

can preserve a person’s ability to enjoy life. Doing this involves reaching a balance between life activities,

Mental health is about not only avoiding active conditions but also looking after ongoing wellness and

world, mental health disorders are one of the leading causes of disability. Social and financial circumstances,
biological factors, and lifestyle choices can all shape a person’s mental well-being. A large proportion of
people with a mental health disorder have more than one condition at a time. It is important to note that
good mental health depends on a delicate balance of factors and that several elements of life and the world
at large can work together to contribute to disorders.

Q1. Given a non-negative integer array Arr having size N. Each element of the array will carry a different
value. This means no two elements can have the same values.The candidate has to do this with minimal
changes in the original value of the elements, making every element as least as much value as it originally
had.

Find the minimum sum of all elements that can be set the array for:
Example 1:
Input
3 -> Value of N, represents size of Arr
2 -> Value of Arr[0]
2-> Value of Arr[1]

om
4-> Value of Arr[2]

Output

.c
9

Explanation: w
no
As two elements have the same value, max value for the one of them needs to be incremented to 3.
He can set the array with 2+3+4=9
rs

Example 2:
he

Input
2 -> Value of N, represents size of Arr
3 -> Value of Arr[0]
es

4-> Value of Arr[1]

5-> Value of Arr[2]
.fr

Output
w

Wrong Input
w

Explanation:
w

Here N=2, so we need to provide value of only two elements but we are providing value of three elements
so result is “Wrong Input”

The Input format for the testing

First input line: Accept a single positive integer value for N representing the size of Arr[]
Second input line: Accept N number of integer values separated by a new line, representing the original
value assigned to each element.

Output Format for testing:

The output must be a non integer only (See the output format example).
Violation of input criteria: System should display message as “Wrong Input”.
Additional messages in the output will result in the failure of the test cases.

Solution in C++:
#include<iostream>
using namespace std;
int main()
{
int n, sum = 0, flag = 0;
cin >> n;
int arr[n];
for(int i = 0; i < n; i++)
{
cin >> arr[i];

om
}
for(int i = 0; i < n; i++)
{

.c
for(int j = i+1; j < n; j++)
{
if(arr[i] == arr[j])
{
w
no
arr[i] = arr[i]+1;
}
rs

if(arr[j] < 0)
flag = 1;
he

}
}
es

for(int i = 0; i < n; i++)

{
.fr

sum = sum + arr[i];

}
w

if(flag == 1)
cout << "Wrong Input";
w

else
w

cout << sum;

Q2. Joseph is learning digital logic subject which will be for his next semester. He usually tries to solve unit
assignment problems before the lecture. Today, he got one tricky question. The problem statement is “A
positive integer has been given as an input. Convert decimal value to binary representation. Toggle all bits
of it after the most significant bit including the most significant bit. Print the positive integer value after
toggling all bits”.
Constraints
1 <=N <=100

Example 1
Input:
10 ---> Integer

Output:
5 → result - Integer

Explanation:
Binary representation of 10 is 1010. After toggling the bits (1010), will get 0101, which represents “5”.
Hence the output will print “5”.

om
Example 2
Input:
101 ---> Integer

.c
Output:
Wrong input → result - String

Explanation:
w
no
Given integer “101” is out of range. Hence the output will print “Wrong input”.
rs

The input format for testing

The candidate has to write the code to accept one input(s).
he

1. First Input - First line contains an integer

es

The output format for testing

1. Print integer value based on the number got after toggling all the bits of given input.
.fr

2. Print “Wrong input if the string length is out of the range.

3. Additional messages in output will cause the failure of test cases.
w

Instructions
w

1. The system doesn’t allow any kind of hard-coded input value.

w

2. Written program code by the candidate will be verified against all the inputs which are supplied from
the system.

Solution in C++:
#include<iostream>
using namespace std;
void toggle(int &n)
{
int temp = 1;
while (temp <= n)
{
 n = n ^ temp;
temp = temp << 1;
}
}
int main()
{
int n;
cin >> n;
if(n <= 100)

toggle(n);
cout << n;

Q3. Given a string S(input) consisting of * and #. The length of the string is variable. The task is to find the
minimum number of * and # required to make it a valid string. The string is considered valid if the number of
rs

* and # are equal. The * and # can be at any position in the string.
he

Note: The output will be a positive or negative integer based on number of * and # in the input string.
es

(* > #) : Positive integer

(# > *) : Negative integer
.fr

(#=*): 0
w

Example 1:
Input
w

###*** → Value of S
w

Output
0 ---> number of * and # are equal

Example 2:
Input
###***# → Value of S
Output
-1 ---> number of # is more than *

Example 3:
Input
#*** → Value of S
Output
2 ---> number of * is more than #

The input format for testing

The candidate has to write the code to accept one inputs separated by a new line.
First input: Accept a string S without any spaces (consisting of only * and #)

The output format for testing

The output should be a positive integer number (check in e.g.s 1, 2 and 3). Additional messages in output
will cause the failure of test cases.
