Given a mountain array arr[] and an integer X, the task is to find the smallest index of X in the given array. If no such index is found, print -1....
Given a set of strings S and a string patt the task is to autocomplete the string patt to strings from S that have patt as a prefix, using a Ternary Search Tree. If no string matches the given prefix, print “None”.Examples:...

Given three array A[], B[] and C[] of N integers each. The task is to find the count of triplets (A[i], B[j], C[k]) such that A[i] < B[j] < C[k]....
Given an integer k and a monotonic increasing sequence: f(n) = an + bn [log2(n)] + cn^3 where (a = 1, 2, 3, …), (b = 1, 2, 3, …), (c = 0, 1, 2, 3, …) Here, [log2(n)] means, taking the log to the base 2 and round the value down Thus, if n = 1, the value is 0. if n = 2-3, the value is 1. if n = 4-7, the value is 2. if n = 8-15, the value is 3. The task is to find the value n such that f(n) = k, if k doesn’t belong to the sequence then print 0....
