problem: LC 20
start: 6:10 pm
end: 6:23pm
status: done✅
approach: use stack and for opening brackets push their closing counter parts, and for closing brackets; pop() the stack, if equal to closing bracket then continue else return false.
problem: LC 1493
start: 11:10 pm
end: 11:27 pm
status: done✅
approach: standard sliding window, carry on with a window with at most one zero, if exceed shrink from left.
problem: 992
start: 10:18 pm
end: 10:37 pm
status: done✅
approach: find atMostKDistinct(k) and subtract with atMostKDistinct(k-1) to get exactly k distinct.
problem: LC 438
start: 2:36 am
end: 2:48am
status: done✅
approach: (same as LC 567) sliding window with fixed length, freqMap and storing indices in List.
problem: LC 239
start: 10:42 pm
end: 11: 34pm
status: done✅
approach: (need to go through neetcode video to understand the logic) deque sliding window, monotonically decreasing queue.
problem: GFG first negative in every window of size k
start: 8:30pm
end: 9:30 pm
status: done✅
approach: started with sliding window with loop approach but could not pass 1111th test case (very last one) so looked up; needed to use deque.
