interview tips

1.) tell soln from BRUTE to BETTER to OPTIMAL

2.) Give good names to fn & var.


3.) Extra Space Used :  given wale ko exclude karke batana hai.

Space Used : given wale ko include karke batana hai.


4.) never deep down in brute solution in interview, just tell upar upar se (IMP)

5.) tell method/steps upar upar se and u need not code in interview also (IMP)

6.) Don't make global variables while solving an interview ques.

-------------------------------------------------------------------------------------------------------------

7. don't change original given thing, instead make a copy of it & work on copy

⭐8. we can simplify our soln by explicitly handling edge cases and making generalized algo for the result

9. in general, interviewer do not ask for time complexity for reccurssion problem, but if asked then tell exponential

10. Do not use pow() function in interview, instead build your own multiplier function,
e.g., in nth root problem, we do not use pow() function since we need exact answer and pow() returns answers in floating point precision.

11. pow() & ceil() function works with floating values and returns answers in double

30.) DP on subsequences

Subset sum = target✅⭐ Partition equal subset sum✅ Partition array into 2 subsets with min abs [sum(v1)-sum(v2) ]✅ Count subsets with sum k✅⭐ Count partitions with given diff✅ target sum✅ 0/1 knapsack✅⭐ min coins✅---->count min coins to be taken coin change-2--->count n(ways) of taking coins⭐✅ unbounded knapsack✅ rod cutting problem✅ ----------------------------------------------------------------------------------------------------------------------------- 2 ways to generate all subsequences- Power Set, or Recursion subset means subsequence in dsa ----------------------------------------------------------------------------------------------------------------------------- 1. Target Sum- QUES- return true if there exists a subset with sum equal to the target in the array... Soln assuming all array elements are positive  here f(n-1,target) will tell if there's a subsequence till n-1 index with sum = target 1.) RECURSIVE SOLN-        ( time: 2^n    ...

19. Strings (LB)

Image
Character Array- 1. We use  1d character array  to simulate strings, e.g., char ch[10]; cin>>ch; 2. string ends with '\0' 3. cin with string works only if till space, tab or new line is absent in input... 4. work with character array just like a normal array, here only datatype is changed to char, else wise it is just an array -------------------------------------------- 5. In-Built functions- - int n = strlen(ch)   - strcmp(s1,s2)            // gives 0 if both strings are equal  - strcpy(dest,source)   // copies a string from dest to source -------------------------------------------- ----------------------------------------------------------------------------------------------------------------------------- STRING- It is a C++ STL 1. has dynamic size (can dynamically increase size when needed) 2. null terminator (\0) NOT required 3. Has built-in functions : - return s.size() - return s == "hello" - return s + "wor...
