1. [12 pts] Consider the following method: public int recursivel( int n, int k) { if ( n == 1 ) { return k; } else { return ( recursivel ( n/2, k++ ) ); } } Part A [5 pts]: Write the recurrence equation for T(n), that is, the running time of this method as a function of input value n. Assume that all arithmetic operations and comparisons take constant time. No justification is required. Part B [7 pts]: Solve the above recurrence equation. Show your work
