I wrote it in C where first I used the pow() function that already is in C. Then I used a for loop, and then the interviewer asked me to do it recursively. pow(): int expo(b,e){ int result; result = pow(b,e); return result; } For loop: int expo(b,e){ int result; result = 0; int x; for(x=0; x0) return b*expo(b, e-1); else return 1; }
