3. Pattern Printing

1. not come in interviews

2. just for practice of loops

3. observe symmetry- if present then write and combine the 2 codes

4. outer loop for row and inner for col entries in a row

5. we just have to somehow connect col to rows.

subtract n from each element of matrix

each new element is minimum distance of that position from every side

top dist = i

left dist = j

right dist = (2n-2)-j

bottom dist = (2n-2)-i

after writing all these again subtract final answer from n to get required answer.

a=min(b,c)

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...
