The minimum number of iterations required to find one defective weight among equal weights.

• Repeat the process with the defective group until the defective weight is found.

Minimum steps to reach end of array

• Use dynamic programming approach

• Start from the end and work backwards

• Keep track of minimum steps at each index

String reversal using recursion

• Define a function that takes a string as input

• Base case: if the length of the string is 0 or 1, return the string

• Recursive case: return the last character of the string concatenated with the result of calling the function with the string minus the last character

Reverse a string program using array of strings

• Create a character array to store the reversed string

• Join the characters in the new array to form the reversed string

Secure way of storing tokens

• Use a secure token storage mechanism like Keychain on iOS or SharedPreferences on Android
