/*remember substring length you are dealing with take only those substrings
chain like pattern -> linked list (or) to from Arrays
finding degree can be done during input scanning itself(ok&=true:false flag trick)
longest subsquence can be solved in O(n) itself incase of consecutive numbers why try all subsequence go o dp[i-1]
(*******consecutive numberssssss*********)
initialize all global variables and collection ds
swapping changes the arr so make sure initialize with the original again(careful from where to start after swapping)
missing out character when comparing ==0 instead of =='0'
keep going until a condition and start off from first ****stack***
meet in the middle algo
one dfs call will tell u the dfs of all nodes
2d prefix array for max occurence of number in a range.also storing positions in case of duplicate numbers can
help bring down the complexity to o(N) and considering ranges based on positions
