Program to check leap year

LEAP YEAR:

A leap year is a year that is divisible by 4, but not by 100, unless it is also divisible by 400. This means that years like 2024, 2020, and 2016 are leap years, but 2100 is not.


PROGRAM:

include <stdio.h>

int main()

{

    int year;

    printf("Enter the year: ");

    scanf("%d",&year);

    if((year%4==0 && year%100!=0) || year%400==0)

    {

    printf("%d is a leap year", year);

    }

    else

    {

    printf("%d is not a leap year", year);

    }

    return 0;

}


TIME COMPLEXITY:

The time complexity of this program is O(1) because the program only performs a fixed number of operations regardless of the input size. The if- else statement and the printf statements are executed once each, making the time complexity O(1).


SPACE COMPLEXITY:

The space complexity is O(1) because the program only uses a constant amount of memory to store the input year and a few variables.

} 


Positive test case

Swap two numbers without using third variable

SWAPPING TWO NUMBERS WITHOUT USING A THIRD VARIABLE There are two common ways to swap two numbers without using a third variable: PROGRAM 1 (Using addition and Subtraction): #include <stdio.h> int main() {     int a,b;     printf("enter the value of a: ");     scanf("%d",&a);     printf("enter the value of b: ");     scanf("%d",&b);     printf("Before swapping, a=%d b=%d.",a,b);     a=a+b;     b=a-b;     a=a-b;     printf("\nAfter swapping, a=%d b=%d.",a,b);     return 0; } PROGRAM 2 (Using Bitwise XOR): #include <stdio.h> int main() {     int a,b;     printf("enter the value of a: ");     scanf("%d",&a);     printf("enter the value of b: ");     scanf("%d",&b);     printf("Before swapping, a=%d b=%d.",a,b);     a=a^b;     b=a^b;     a=a^b;     printf("...

Check a number is palindrome or not

Image
PALINDROME: A palindrome is a word, phrase, or sequence that reads the same backward as forward.  A number palindrome is a numerical palindrome, where the digits read the same when reversed. For example, 12321 is a palindrome whereas 12345 is not a palindrome. PROGRAM: #include <stdio.h> int main() {     int n,m,rem,rev=0;     printf("Enter any number: ");     scanf("%d",&n);     m=n;     while(n!=0)     {         rem=n%10;         rev=rev*10+rem;         n=n/10;     }     if(rev == m)     printf("%d is a palindrome", m);     else     printf("%d is not a palindrome",m);     return 0; } TIME COMPLEXITY: The time complexity of the program is indeed O(log n) because the number of iterations in the while loop is proportional to the number of digits in the input number 'n'. As the number of digits in...
