WebApr 10, 2024 · Algorithm to find the Cube Root using Binary Search. STEP 1 − Consider a number ‘n’ and initialise low=0 and right= n (given number). STEP 2 − Find mid value of low and high using mid = low + (high-low)/2. STEP 3 − find the value of mid * mid*mid, if mid * mid*mid == n then return mid value. WebIf we provided a “true” non-const iterator, it would allow reassigning data in the tree: bstree::iterator it = myTree.find(50); *it = 10000; which would very likely break the internal ordering of data, violating the binary search tree property, and making it useless for any future searches.
