USE # TO MAKE SURE PREPROCESSOR DIRECTIVES ARE PRESENT ALSO REFER THE IMAGE ATTACHED LINK: /predownloaded/a4/5d/a45dca13af722302fb8e0c3d6064392213c999c4.jpg hi Everyone Here is a template i managed to get from some famous people

copy the code below: ok lets start with shortcut. vl = vector vll = vector<vector> vc = vector; vs = vector how to use? lets declare a vector long long: vll arr; similarly vs arr1; vc arr2;

some other shortcuts: for loop shortcut +ve for loop fp(i,start,end){ // some code; } i = variable to use; start = starting point; end = ending point + 1;

-ve for loop: fn(i,start,end){ // some code; } i : variable start : start point; end : end point -1;

for debuging ure code: make a document name as "error.txt"

lets have a variable: int a = 10 int b = 19; vl arr = {1,2,3,4,6}; vc arr1 = {'a','b','c'}; //lets debug

debug(a); debug(b); debug(arr); debug(arr1);

//expected output on error.txt // a 10 // b 19 // arr [ 1 2 3 4 5 6 ] // arr1 [ a b c ]
