Operators and For Loop

 Bitwise operator -


Bitwise operators ko istemal karke aap integers ke alag-alag bits par operations kar sakte hain. Java mein, kuch aise bitwise operators hote hain jo aapko numbers ke alag-alag bits ko manipulate karne aur shifting aur masking jaise alag-alag operations perform karne ki anumati dete hain.

Yahan par Java mein common bitwise operators hain:

AND (&): Ye corresponding bits ke beech mein bitwise AND operation perform karta hai. Result bit sirf tab 1 hoga jab dono input bits 1 honge.

OR (|): Ye corresponding bits ke beech mein bitwise OR operation perform karta hai. Result bit 1 hoga agar kam se kam ek input bit 1 hoga.

XOR (^): Ye corresponding bits ke beech mein bitwise XOR (exclusive OR) operation perform karta hai. Result bit tab 1 hoga jab input bits alag honge.

NOT (~): Ye ek integer ke individual bits par bitwise NOT operation perform karta hai, jiske wajah se saare bits flip ho jate hain (1s 0s ban jaate hain aur vice versa).

Left Shift (<<): Ye ek integer ke bits ko left mein di gayi positions se shift karta hai. Naye bits jo right side par aate hain, unko zero se fill kiya jata hai.

Right Shift (>>): Ye ek integer ke bits ko right mein di gayi positions se shift karta hai. Leftmost bits mein sign bit (signed numbers ke liye) ya phir zero (unsigned numbers ke liye) fill kiya jata hai.

Unsigned Right Shift (>>>): Right shift operator ke jaisa hai, lekin yahan leftmost bits ko zero se fill kiya jata hai, chaahe number ka sign kaisa bhi ho.

Ye bitwise operators operands ke individual bits par kaam karte hain, jo integers ya dusre numeric data types ho sakte hain. Ye aksar low-level operations ke liye istemal hote hain jaise ki code ko optimize karna, hardware ke saath kaam karna, ya bit-packed data structures ke andar individual flags ko set ya clear karna.

 Q- how to Print Hello World print("Hello World") Variables in python ------- age = 30   #variable should be intutive so that we can learn any time print(age) Note: Shift+Enter is shortcut to run command 2) ' #' this is for writing the comment in python Rules for Variables--- Variable can not be start with any number like - 1age  Number can use in between and end with variable like - age1 age2 Special characters are not allowed expect _ (underscore) like - age_my Space not allowed in variable  Python is case sensitive  Way to define Variable --- age1,age2 = 30,25  age1 = 30 age2 = 25 age1=age2=30   #if 30 age for both variable   >> Data type the type of data is basically data type Integer = age1 to age3 is basically integer   , Integer is basically full number lets check = type(age1)  #it will give u print int float=  basically decimal values Interest =  30.24 type(Interest) #answer is float Message = ...

Indexing--  it will help u to fetch single character  string= "Python" string[2] # slicing process of fetching a sub-string from the given string  #sequence of charater we can fetch means more than 1 character string="Divyanshu" string[2:4+1]   #basically here number is index value #string[start_index:end+index+1] string = "Hunny"   #indexing agr positive hai to left se count hoga #right se negative me string[:]  #it will give u entire string #now If i want to any characterwise index like string is Hunny and I want un only #string[start_index:end_index+1:step] string[1:4:2] #reverse your string #string[:: -1] string="Baba hunny" string[:: -1] # to convert into lowecase string="New Divyanshu" new_string=string.lower()  #new_string becase we've to create another string print(new_string) s1={1,2,3,4,5}    s2={3,2,8,67,85} s3=s1.union(s2) s3   #isme add hota hai whole value lekin common value update nhi hongi #intersection - ...
